Voron 2.4 R2 (LDO Rev D+, 350) — Printed Parts Plan¶

Print every part on the Prusa Core One+, Prusament ASA, plate by plate, in build order. Written to be followed with a 13-year-old: one plate = one job.

Totals at a glance: 22 plates · 157.0 h print time · 1813 g Galaxy Black + 279 g ASA Blue · against 2400 g black + 800 g blue on hand. PrusaSlicer 2.9.6 estimates, sliced from the committed projects in slicer/plates/ (§4.1); they replace a throughput model that read 134.3 h / 2248 g. Plus B11, the bay ducting, outside those totals: 5 plates · 25.0 h · 348 g Jet Black PETG V0 (§3, §9).

Revali, three-quarter — One plate is one job. That is the entire plan. Making it look this simple took a champion.

0. What kit you actually have (established facts, with sources)¶

Everything below is from LDO's or Fabreeko's own pages, not from blogs.

Fact	Value	Source
Kit	LDO Voron 2.4 R2 Rev D+, 350 mm	Fabreeko product page
What "Rev D+" changes vs Rev D	"Nitehawk SB update with USB passthrough for USB based eddy current probes" (Mar 2026). Mostly electrical — one printed-part change: the V2 board's USB-adapter cover is `MotorDynamicsLab/Nitehawk-SB-V2/STLs/usb_adapter_mount_partial_cover.stl` (ground-lug mount), not the V1 `usb_adapter_mount.stl` cover — see batch B07.	Fabreeko
Mainboard	LDO Leviathan (5× TMC2209 + 2× TMC5160HV for A/B, 48 V capable, integrated Raspberry Pi mount)	Fabreeko; LDO wiring guide Rev D
Toolhead board	Nitehawk-SB V2 (STM32G0B1; USB toolhead PCB, integrated ADXL) — the "+" in Rev D+	LDO Voron 2.4 kit page
Bed probe	Omron inductive probe included AND a Klicky Probe Kit included — you pick one. LDO: "Instead of the included Omron inductive probe, we also provide the parts to build your machine using the optional Klicky mod by jlas1." Wiring guide: "Connect the inductive probe or Klicky cable to the PROBE port."	LDO kit page; Rev D wiring guide; Rev D 350 BOM lists "Klicky Probe Kit ×1"
Z endstop	LDO nozzle-probe PCB; the printed part `nozzle_probe_ldo.stl` is supplied printed in the kit	Rev D printed parts guide
XY endstop	D2F microswitch PCB — print `[a]_endstop_pod_D2F_switch`, not the hall-effect pod. No hall effect anywhere in this kit.	Rev D printed parts guide; Build Notes p.145
Screen	BigTreeTech Pi TFT4.3 (4.3" capacitive DSI). Print the LDO BTT Pi TFT4.3 Mount; do not print the mini12864 parts.	Rev D printed parts guide; Rev D 350 BOM
Filtration	Nevermore Micro V5 Duo (6×3 mm magnets), instead of the stock Voron exhaust filter. Stock exhaust housing is NOT built; the back panel is sealed with LDO's `exhaust_cover` + the stock `exhaust_filter_grill`. Carbon not included.	LDO kit page; Rev D printed parts guide; LDO Nevermore guide
Hotend	E3D Revo High-Flow (Revo Voron form factor) → Stealthburner printhead files `revo_voron/*`	Fabreeko; SB printhead compatibility table ("E3D Revo Voron → E-RV")
Cable chains	2-hole ends → always take the `_2hole` variants, never `_3hole`	Rev D printed parts guide
Power inlet	1.0 mm AC inlet with integrated switch → `power_inlet_IECGS_1mm.stl`	Rev D printed parts guide
Panels	Deck 3 mm acrylic, back 3 mm acrylic, bottom 4 mm acrylic, doors/sides/top 3 mm PC. Foam tape 1 mm and 3 mm both supplied.	Rev D 350 BOM
Rails	1× stainless MGN12H 400 (X) + 6× stainless MGN9H 400 (2× Y, 4× Z) → print both rail guides	Rev D 350 BOM
Printed parts included	NOT included with the kit — except the ten LDO parts listed in §7	Fabreeko
Clicky-Clack door kit	Hardware + extrusions only. STLs come from GitHub, panel bought separately (you did).	Fabreeko Clicky-Clack page
Titanium backers	Gantry X/Y extrusion stiffeners; no stock STL changes. Fabreeko's set ships pre-tapped for the cable chain. See §6 note.	Fabreeko backers; whoppingpochard backer README

Parts where the kit revision changes the STL — all three already resolved above, but flag them if the kit that arrives is not Rev D/D+:

Mainboard bracket. Rev C and earlier shipped a BTT Octopus → Octopus_bracket_set.stl. Rev D ships Leviathan → Leviathan_bracket_set.stl (supplied printed). If a Rev C kit arrives, print the Octopus set.
Raspberry Pi mount. Rev C needed beefy_raspberry_bracket.stl; LDO Build Notes p.150 explicitly say "it does not apply for rev D kits" — Leviathan carries the Pi. Print nothing.
XY endstop pod. Rev A/B kits used a hall-effect endstop → [a]_endstop_pod_hall_effect.stl + z_joint_upper_hall_effect.stl. Rev C/D use the D2F PCB → [a]_endstop_pod_D2F_switch.stl + 4× plain z_joint_upper_x4.
Display. Rev A used the mini12864 skirt module; Rev C/D use the BTT touchscreen mount. Different front-skirt module entirely.
Plug panel. power_inlet_IECGS_1mm (Rev C/D, 1.0 mm inlet) vs _1.2mm vs power_inlet_filtered. LDO's own plug_panel_1.2mm.stl is marked deprecated for 2.4R2.

Resolved 2026-09-05: Rev D+ = Rev D + Nitehawk-SB V2 — electrical plus one printed part (usb_adapter_mount_partial_cover, batch B07). The Rev D printed-parts guide applies for everything else. LDO still publishes no "Rev D+" printed-parts page (printed_part_guide_rev_d_plus returns 404); the only open question for the Fabreeko Discord is whether one will ever be published.

The Voron repos have no release tags; take the branch head and record the commit SHA in a text file next to your STLs so a mid-build reprint is identical to the first print.

1.2 Colour key (Voron's own naming convention)¶

From the 2.4r2 Assembly Manual p.4–5 and the Stealthburner STL README:

Prefix	Meaning	Our filament
(none)	Primary colour	Prusament ASA Galaxy Black
`[a]_`	Accent colour	Prusament ASA Blue
`[o]_`	Opaque — must block light	Galaxy Black (perfect)
`[c]_`	Clear / translucent	Do not print — LDO supplies the SB LED diffuser in clear PETG
`_x#` suffix	Quantity required to build the machine	e.g. `z_joint_lower_x4.stl` → print 4 copies of the file

The _x# number is a quantity, not a hint that the file contains that many bodies. I checked every file: only these contain more than one body — [a]_stealthburner_main_body (7 — built-in supports), cw2_captive_pcb_cover (2), usb_adapter_mount (2 — mount base + cover), Leviathan_bracket_set (2 — L+R), bottom_panel_hinge_x2 (2), cob_light_strip_mount_* (2 — the mount is a 2-piece assembly), V2_Duo_Plenum (2 — built-in support). Clicky-Clack's Hinge-L-sleeve-2X / -solid-2X contain one body each — "2X" means print two.

1.3 Slicer: PrusaSlicer profile and the Voron overrides¶

Slicer: PrusaSlicer 2.9.6 (current stable, released 2026-06-25 — GitHub releases). 3.0.0-alpha12 shipped 2026-09-21 as an early preview. Version posture (ruling 2026-09-26): every batch, B00 through B11, is sliced on 2.9.6; the 3.0 preview is not used for this build. Any toolchain change re-runs Gate A and Gate B (§1.4). The 3.0 deltas are kept as reference in docs/manual/print/00-slicer-setup.md.

Base profiles — the ones every committed 3MF and both .ini bundles carry (verified against PrusaResearch.ini @ version_2.9.6). The machine has the high-flow 0.4 nozzle, so the HF0.4 variants are the base; 00-slicer-setup owns the full reasoning:

Printer: Prusa CORE One HF0.4 nozzle (printer model Prusa CORE One & CORE One+) — bed 250×220, max height 270, retract 0.7 mm @ 45 mm/s, z-hop 0.2 mm, wipe off. The projects carry the cold-probe start G-code, so the Plater shows it as (modified).
Filament: Prusament ASA @COREONE HF0.4 — nozzle 265 °C, bed 110 °C, chamber 55 °C (minimum 40 °C), fan 20–25 %, first 4 layers fan off, density 1.07 g/cm³, max volumetric 26 mm³/s. The projects save it as Prusament ASA @COREONE HF0.4 - Voron black (accent: - Voron blue).
Print: 0.20mm STRUCTURAL @COREONE 0.4 — not SPEED. There is no HF0.4 STRUCTURAL at 0.20 mm; this non-HF print preset is offered on the HF printer and is the one the projects use. STRUCTURAL is already the quality-biased profile (perimeters 70 mm/s vs SPEED's 170; external 50 vs 170; infill 120 vs 200).

Overrides. Column "source" = where the number comes from; judgment = my call, not a cited spec.

Print settings¶

Setting	Prusa STRUCTURAL default	Set to	Why	Source
Layer height / first layer	0.20 / 0.20	keep	Voron spec	Manual p.4
Perimeters	2	4	Voron spec; wall count is what carries load in these parts	Manual p.4
Top solid layers	5	keep 5	Voron spec	Manual p.4
Bottom solid layers	4	5	Voron spec says 5 top and bottom	Manual p.4
Fill density	15 %	40 %	Voron spec	Manual p.4
Fill pattern	Grid	keep Grid	Voron allows grid/gyroid/honeycomb/triangle/cubic	Manual p.4
Extrusion width (default, perimeter, external, infill, solid)	0.45	0.40	Voron: "Extrusion width — Recommended: Forced 0.4 mm". Ribs, bosses and bearing seats were drawn around a 0.4 bead.	Manual p.4
First layer extrusion width	0.50	keep 0.50	wider first bead = better ASA adhesion	judgment
Top infill extrusion width	0.42	0.40	consistency	judgment
Perimeter generator	Arachne	keep Arachne	Voron's "forced 0.4" predates Arachne. Arachne varies bead width on purpose and handles Voron's thin ribs better than Classic. Setting nominal width to 0.4 gives Arachne the right target.	judgment
Supports	on (auto off)	None	Every Voron/LDO/Nevermore STL is pre-oriented with built-in break-away supports where needed	Manual; Nevermore README; Klicky STL README
Seam position	Aligned	Rear	keeps the seam off the visible outward faces of skirts and the toolhead	your build spec
Skirt loops	0	1 loop, 3 mm gap, min length 4 mm	primes after the long ASA purge; lets you abort in the first 60 s if the first layer is wrong	judgment
Brim	off	off by default; 5 mm on the tall/narrow parts, 3 mm on the 150–182 mm skirts — list in §5	ASA corner lift on long flat parts and tippy tall parts	Prusa warping KB; judgment
XY size compensation	0	keep 0	Voron: "The parts have been designed with ABS/ASA shrinkage in mind… shrinkage should be set to 100 %. Compensating for this is likely to make bearing fits and screw holes too large."	docs.vorondesign.com/materials.html
Elephant-foot compensation	0.20	keep 0.20 for now, verify on the cube	it shrinks only the first layer; several Voron parts have a bearing bore starting at the bed. Measure before changing.	judgment
External perimeter speed	50	35	surface finish and corner accuracy on the visible skirts; speed is not a goal here	judgment
Perimeter speed	70	55	more time at temperature per bead = better interlayer bond at 4 walls	judgment
Infill speed	120	100	interior quality and less pressure variation into the perimeters	judgment
Solid infill speed	140	110	flatter top/bottom faces on the skirts	judgment
Top solid infill	80	keep 80	already conservative	—
First layer speed	45	25	ASA on smooth PEI is the single biggest failure mode; slow the first layer	Prusa ASA KB; judgment
External perimeters first	off	keep off	inside-out gives better dimensional accuracy on holes; only flip it if you see external-perimeter bulging	judgment
Dynamic overhang speeds	on (15/25/45/90 %)	keep on	Prusa tuned these for the Core One's part fan	—
Ironing	off	keep off	—	—

Filament settings (Prusament ASA @COREONE HF0.4)¶

Setting	Profile default	Set to	Why	Source
Shrinkage compensation XY	0.22 %	0 %	Same rule as XY size compensation — PrusaSlicer 2.9 scales ASA parts up 0.22 %; that is +0.15 mm on a 66.7 mm Z-drive body and +0.035 mm on every 16 mm bearing bore, compounding with any flow error. This is the single most important override in this document.	docs.vorondesign.com/materials.html + profile value
Shrinkage compensation Z	0.22 %	0 %	same reason	as above
Nozzle / first-layer nozzle	265 / 265 °C	keep	Prusa's own Prusament ASA values for the HF nozzle on this machine	profile
Bed / first-layer bed	110 / 110 °C	keep	Prusa ASA guidance is ≥100 °C bed	profile; Prusa ASA KB
Chamber temperature	55 °C	keep 55	matches the 55–60 °C a real Voron sees; the Voron parts are designed for it	profile; docs.vorondesign.com/materials.html
Chamber minimal temperature	40 °C	keep 40	printer will not start until the chamber reaches 40 °C — this is your preheat gate	profile
Min / max fan	20 / 25 %	keep for B00–B01, then decide	Prusa tuned this for the Core One chamber. If you see perimeter separation on the Z-drive bodies, drop to 0 / 15 % and keep bridge fan at 25 %.	profile; Ellis — Perimeter Separation
Max volumetric speed	26 mm³/s	keep	not a limit at these speeds (peak ≈8.8 mm³/s)	profile
Retraction / z-hop	0.7 mm / 0.2 mm	keep	Nextruder-specific; do not touch	printer profile

Drying¶

ASA is mildly hygroscopic. A fresh, sealed Prusament spool used within ~2 weeks needs nothing. Dry at 80 °C for 4 h if a spool has been open longer, or the moment you see stringing, matte striping, or popping; on the Sunlu SP2 (70 °C cap) that is 70 °C for 6 h with the port plugs out. Keep the active spool in one USS Drybox during the run. Voron parts are structural — this is the material where wet filament actually costs you strength. (Sources: Prusa ASA KB; the project's drying rules, AGENTS.md › Materials & filament.)

1.4 Calibration sequence — run this before B00, and again after any toolchain change¶

Advanced Filtration Kit — already fitted (2026-09-12), so there is nothing to install here. You're about to run ~157 h of ASA in an enclosure: on the first ASA plate confirm the blower runs and the bypass flaps seal. One spare cartridge is still to buy (~600 print-h each, 1–2 wk Prusa lead time).
Firmware ≥ 6.8.1 on the Core One+. It runs 7.0.0 (2026-10-05), the first non-INDX release after 6.8.1.
First layer: there is nothing to run. The Core One+ has no first-layer calibration wizard — the Nextruder loadcell sets Z automatically before every print, as part of mesh bed levelling (Prusa KB — Live Adjust Z). Judge B00-P1's first layer by Ellis' smooth-bottom method: smooth, no visible gaps between beads, no ridging. If it needs a nudge, long-press the knob during the first layer → Live Adjust Z — and note the nudge is not saved for the next print, so fix the cause (sheet seating, glue film, nozzle seat) rather than nudging every plate.
Print plate B00-P1 (§3). It carries the coupons for both gates.
Measure with the calipers, at mid-height (not across the first layer). The gate is in two parts, because three coupons need parts that only arrive with the Voron kit.

Gate A — no kit needed (the cube):

Coupon	Nominal	Accept	If out of spec
`Voron_Design_Cube_v7` X and Y	30.00 mm	±0.15 mm	>+0.15: confirm shrinkage compensation is 0 % and XY compensation is 0. Still over → reduce extrusion multiplier in 1 % steps (Ellis — Extrusion Multiplier). Do not dial in negative XY compensation; you will wreck the bearing fits.
`Voron_Design_Cube_v7` Z	30.00 mm	±0.10 mm	over → first layer under-squished; under → over-squished
Cube first layer vs mid-height X	—	difference ≤ 0.15 mm	bigger → elephant-foot compensation is wrong; adjust in 0.05 mm steps
Cube corner snap test	—	must not delaminate along a layer line	delamination → chamber too cold or fan too high → drop min/max fan to 0/15 %

Gate B — inserts and a caliper now, on what is already on the bench; bearing and rail on kit day:

When	Coupon	Nominal	Accept	If out of spec
now	`Heatset_Practice`	7 × M3×H5 inserts from the KADRICK kit, all seven pockets (all 153 kit inserts stay for the build)	insert sits flush to 0.2 mm proud, boss does not bulge > 0.2 mm	bulging → iron too hot or pushed too fast; this is a technique problem, not a slicer one. This coupon is the adult's practice part and has no other use: Ch 00 Steps 00.14–00.15 are this row. Set all seven before touching a real part. The iron stays with the adult; once the coupon has cooled, the helper reads the caliper on each insert and calls flush or proud.
now	`z_drive_retainer_a` 625-2RS pocket (on the same plate)	16.30 mm, measured off the STL	caliper reads 16.30 mm ±0.15	over → confirm shrinkage compensation is 0 % and XY compensation is 0, then raise extrusion multiplier 1 %. Under → reduce it 1 %. Reprint the retainer and the cube, re-pass Gate A.
kit day	the same pocket, on a real 625-2RS (16 mm OD; F695 is the A/B-drive bearing, not the Z drive)	—	bearing presses in with thumb pressure, no rocking	The press fit the caliper stood in for.
kit day	`MGN12_rail_guide` on the real MGN12 rail	—	slides on with light finger pressure	very tight → over-extrusion; loose → under-extrusion

Gate A passed → B02, B07 and the cosmetics B08 → B09 → B10 are released (the whole run prints on the current Gen 1 GT2 belts — §8). Gate B passed → B01, then B03–B06. Never start B01 or B03–B06 on Gate A alone — that is 58.4 h and 763 g of bearing-seat and bore parts against an unverified fit. Nothing is bought to bring Gate B forward: its insert row runs on the KADRICK inserts already on the bench and its bore row is a caliper, so both run in the same week as Gate A. The bearing press and the MGN12 rail row wait for the kit, and the rail row gates nothing but a 20-minute reprint of the MGN12_rail_guide jig.

Quality gate before every later batch: look at the last plate you pulled off. If any part shows (a) a lifted corner, (b) a delaminated layer, or (c) a bore/boss that failed a test fit — fix that before starting the next plate, don't print 100 g on top of a known problem.

2. Which parts gate the frame and Z-drive steps¶

Frame (Assembly Manual ch. Frame, p.12–21): no printed part is required. The frame is extrusion, corner brackets and hardware. You can square the frame the day the kit lands — and by then every plate in the build is already printed and binned.

Z rails (p.24–27, inside ch. Z Drives and Idlers): the only printed items are the optional-but-worth-it alignment jigs — MGN12_rail_guide_x2 ×2 and MGN9_rail_guide_x2 ×2. Both are on plate B00-P1.

Z Drives and Idlers (p.22–51) — the first step that genuinely stops without plastic. It needs:

all of Batch 1 (Z-drive bodies, retainers, motor mounts, Z-tensioner brackets, deck supports), and
these accent parts from Batch 2: [a]_z_drive_baseplate_a/b ×2 each, [a]_belt_tensioner_a/b ×2 each, [a]_z_tensioner_9mm_x4 ×4.

So the minimum to start building is B00 + B01 + B02-P1 + B02-P3 ≈ 34 h of printing. Everything else can be printed while you build.

What prints before the kit: all of it. Fabreeko's kit is not expected before late November 2026 (§8), and with Gate B's caliper and insert rows run early on what is already on the bench (§1.4) nothing is left to gate a batch. The order is therefore the plain numeric one — pre-B00 checks on the current Gen 1 belts, then B00 → B01 → B02 → … → B10, 157.0 h ≈ 16 printer-days ≈ 3–4 weeks at two plate swaps a day. On kit day the frame (no printed part) and Ch 00 start at once with every bin full, and no assembly chapter ever waits on a plate. The only print job the build may still owe is the deck_support_4mm reprint, if the deck panel calipers 4 mm (§6).

Tall parts (> 150 mm in Z): none. The tallest part in the whole set is the Clicky-Clack Handle at 60.0 mm. Orientation rules that do matter are in §5.

3. The batches¶

Format for each: what it unlocks (manual chapter name), plates, hours, grams, then the parts table (exact filenames, repo path, qty, colour, grams and hours per copy).

Batch headers and plate lines are PrusaSlicer 2.9.6 estimates — sliced from the committed projects in slicer/plates/, with this build's overrides, the real arrangement and the real brims (§4.1). The per-copy g ea / h ea columns inside the parts tables are still the older geometry model, kept for relative sizing only; they do not sum to the plate line, which also carries skirt, brim and travel.

Batch B00 — Calibration & jigs · 1 plate · 4.0 h · 52 g black¶

Unlocks: Frame (rail installation aids) — and gates every batch after it.

STL	Repo path	Qty	Colour	g ea	h ea
`Voron_Design_Cube_v7.stl`	Voron-2 `STLs/Test_Prints/`	1	Black	16.2	0.98
`Heatset_Practice.stl`	Voron-2 `STLs/Test_Prints/`	1	Black	6.5	0.39
`MGN12_rail_guide_x2.stl`	Voron-2 `STLs/Tools/`	2	Black	3.2	0.20

`z_drive_retainer_a_x2.stl`	Voron-2 `STLs/Z_Drive/`	1 (of the 2 needed)	Black	19.5	1.15

Plate B00-P1 — all of the above. 4.0 h, 52 g. The z_drive_retainer_a here is deliberate: it is your bearing-press-fit coupon, and it is a real part you will use, so nothing is wasted.

Batch B01 — Z drive assemblies · 2 plates · 22.8 h · 301 g black¶

Unlocks: Z Drives and Idlers (p.22–51) and the deck-panel step (p.28–30).

STL	Repo path	Qty	Colour	g ea	h ea
`z_drive_main_a_x2.stl`	Voron-2 `STLs/Z_Drive/`	2	Black	39.4	2.31

`z_drive_retainer_b_x2.stl`	Voron-2 `STLs/Z_Drive/`	2	Black	19.5	1.15
`z_motor_mount_a_x2.stl`	Voron-2 `STLs/Z_Drive/`	2	Black	11.9	0.75

`z_tensioner_bracket_b_x2.stl`	Voron-2 `STLs/Z_Idlers/`	2	Black	13.0	0.79
`deck_support_3mm_x8.stl`	Voron-2 `STLs/Panel_Mounting/`	8	Black	1.1	0.07

Plate B01-P1 (15.2 h, 201 g): z_drive_main_a ×2, z_drive_main_b ×2, z_drive_retainer_a ×1, z_drive_retainer_b ×2. Longest plate in the build — start it in the morning, not at bedtime.
Plate B01-P2 (7.6 h, 100 g): z_motor_mount_a ×2, z_motor_mount_b ×2, z_tensioner_bracket_a ×2, z_tensioner_bracket_b ×2, deck_support_3mm ×8.

Deck supports (verify): LDO's Rev D printed-parts guide says "Our kit ships with 4 mm deck panels, use 4 mm deck support clips", but the Rev D 350 BOM lists the deck panel as 3 mm acrylic (the 4 mm panel is the bottom panel). The size-specific 350 BOM wins: print deck_support_3mm_x8 ×8, and if the deck panel measures 4 mm when it arrives, reprint deck_support_4mm_x8 — 8 g, 30 minutes. (guide, BOM, Build Notes p.29-30)

Batch B02 — The accent day (every accent part in the build) · 3 plates · 21.9 h · 279 g blue¶

Unlocks: the accent half of Z Drives and Idlers, A/B Drives and Idlers, Gantry, Stealthburner, Skirts and the Clicky-Clack door.

All 49 accent parts are printed in one continuous blue session so the accent spool is mounted exactly once. Two colour changes in the whole build: black → blue here, blue → black after. Everything is printed before the kit arrives anyway, so nothing waits on this.

Plate B03-P1 (8.5 h, 119 g): both sides — a_drive_frame_lower, a_drive_frame_upper, front_idler_right_lower, front_idler_right_upper, b_drive_frame_lower, b_drive_frame_upper, front_idler_left_lower, front_idler_left_upper.

A and B were on separate plates until 2026-09-06, when the two were merged to cut a plate swap. The trade is real: a failed plate now costs both drive units instead of one, so watch the first layer before walking away.

Plate B04-P1 — all seven. 8.6 h, 117 g.

probe_retainer_bracket is only used if you run the Omron inductive probe. It costs 0.5 g — print it, decide later. If the probe barrel measures 9 mm rather than 8 mm, print probe_retainer_bracket_9mm.stl instead (verify on arrival). x_frame_V2TR_MGN12_* are the R2 / Clockwork-2 carriage halves — LDO Build Notes p.129-130 warn specifically about using the wrong X-carriage here.

Print 4× z_joint_upper_x4 and zero z_joint_upper_hall_effect.stl — that variant exists only for hall-effect XY endstops, which this kit does not use (LDO Build Notes p.145). The LDO z_rail_stop is optional but stops a Z carriage from falling off the top of a rail and spilling its balls.

Plate B06-P1 (12.1 h, 148 g): the Stealthburner + Clockwork 2 black parts and the whole Klicky set, 19 objects. Merged 2026-09-06 from two plates to cut a swap.

Notes: - Hotend file choice is settled: E3D Revo Voron → the revo_voron folder, ..._rear_cw2 for Clockwork 2 (SB printhead README). - Do not print an ADXL mount — the Nitehawk-SB has one on board (LDO Rev D guide). - Do not print the CW2 chain anchor — the kit supplies "CW2 Chain Anchor Tilted" printed (Rev D 350 BOM). - cw2_captive_pcb_cover is LDO's improved cable door (captive screw + external chamber thermistor); the stock alternative is Clockwork2/cable_door_for_pcb.stl if you'd rather. - Klicky dock: fixed mount chosen for simplicity. If you later add the Decontaminator purge bucket, you need Dock_sidemount_fixed_v2.stl + Dock_sidemount_left_v2.stl instead (~25 g, 1.5 h). - The Probe_*_pressfit_helper / _holder parts are jigs for pressing the 6×3 magnets in square. Print them — a crooked magnet is a probe that doesn't repeat. (Klicky "What to print")

Batch B07 — Electronics bay + lighting · 2 plates · 16.0 h · 226 g black¶

Plate B07-P1 (7.9 h, 102 g): wago mount, PSU brackets ×2, PSU stabilizer, USB adapter mount, usb_adapter_mount_partial_cover (ground-lug mount, est.), DIN clips, handlebar spacers ×4, power_inlet_IECGS_1mm.
Plate B07-P2 (8.1 h, 124 g): the eight COB light-strip mounts, brimmed. Nothing else fits.

Notes: - COB counts are LDO's own for a 2.4-350: 6× 100 mm + 2× 50 mm (COB README). Each STL contains a 2-piece assembly joined with 2× M3 heat-sets + 2× M3×6 FHCS. This is the heaviest single group of "small" parts in the build — 127 g. - PSU_stabilizer_50mm is marked (verify): LDO Build Notes say "PAGE 169 SKIP — the kit does not use a support bracket", which most likely refers to this part. It is 4 g; print it and only fit it if it's needed. - Do not print raspberrypi_bracket.stl, beefy_raspberry_bracket.stl or rs25_psu_bracket.stl — Leviathan carries the Pi and there is no 5 V PSU in this kit (Build Notes p.150, p.152). - Do not print the Leviathan bracket set or the bed WAGO mount — both supplied printed. - power_inlet_IECGS_1mm lives here, not in B08, because it's fitted in Ch 09 (p.156/167) — see docs/manual/09-electronics-bay.md. - It cannot ride on B07-P2: with the mandated 3 mm brims the eight COB mounts plus the 118 × 66.8 mm inlet come to 46 280 mm², 84 % of the 250 × 220 bed, and no placement exists. It had a plate to itself until 2026-09-06, when the outline packer proved it fits on B07-P1 at a 6 mm gap, saving a swap.

Batch B08 — Skirts and front modules · 4 plates · 29.2 h · 399 g black¶

Unlocks: Skirts (p.212–239).

The skirt ring is made of ten structural segments plus two "module" pieces — the TFT mount and the power inlet — that all share a 67–72 × 20 mm cross-section. On the 350 the ring works out as: front = front_skirt_a + TFT mount + front_skirt_b; rear = rear_center_skirt + power_inlet + keystone_panel; each side = side_skirt_a + side_fan_support + side_skirt_b.

B08-P4 (5.0 h, 70 g): side_skirt_b_350 ×1, keystone_panel

Every one of these is 117–182 mm on its long axis and 67–72 mm deep. Packed on bounding boxes that meant two per plate; packed on the real outlines (slicer/nest.py, 6 mm between silhouettes plus each part's brim) the C-shaped segments interleave and the set fits on four plates instead of six — the 2026-09-06 consolidation. power_inlet_IECGS_1mm is not here: it moved to B07 (Ch 09, not the skirts chapter). These are the parts people see. They print on the current Gen 1 GT2 belts, in numeric order like every other batch — the Gen 2 belt upgrade is deferred to the INDX rebuild this winter (§8).

Notes: - mount.stl vs mount_thick.stl: mount.stl is 30 g / 44.8 mm tall; mount_thick.stl is 74 g / 67.8 mm and gives access to the screen's brightness buttons with a pointy tool. mount.stl is the recommendation — swap if you find you want the buttons (judgment; LDO links the folder, not a specific file) (mount README). - Do not print mini12864_case_front/rear, [a]_mini12864_case_hinge, [a]_mini12864_case_front_insert, [a]_btt_knob_light_shield — the touchscreen mount replaces that whole front module (LDO Rev D guide). - Optional: [a]_fan_grill_open_optional_x2 (more airflow, less filtering) instead of [a]_fan_grill_a/b; ldo_bestagon_insert (in B02) snaps into the skirt hexagons — print more copies if you like the look.

Why both 4 mm and 6 mm panel clips. The manual mounts back and top panels with 1 mm foam tape (3 mm panel + 1 mm tape = 4 mm) and side panels with 3 mm foam tape (3 + 3 = 6 mm, "to prevent the gantry from rubbing on the panels"). Counting the clips in the manual's own illustrations: back panel 4 corner + 3 midspan, top panel 4 corner + 4 midspan → exactly the _4mm_x8 / _4mm_x7 quantities; each side panel 4 corner + 4 midspan → exactly the _6mm_x8 / _6mm_x8 quantities. (Manual p.239–244; the _x# filename suffix is the authoritative count.) This mapping is an inference — neither Voron nor LDO states which clip goes on which panel. The arithmetic lands exactly, so I'm confident, but snap one clip of each thickness onto an extrusion with a 3 mm panel offcut and the right foam tape before you commit to printing all 31.

Nevermore V5 Duo, exactly which files. The Voron-2 plenum/lid are STLs; the cartridge and its lid are 3MF files in the same folder (PrusaSlicer imports them fine). Use the Regular cartridge, not XL — XL wants carbon pellets and a faster/louder fan. 8× 6×3 mm magnets, 6× M3 heat-sets. The cartridge has a built-in support you push out. (Nevermore README, LDO Nevermore guide)

Exhaust: you are not building the Voron exhaust filter (76 g, 4.5 h saved). LDO: "print this exhaust cover with the stock exhaust grill to seal the back panel" — that is exhaust_cover.stl (LDO) + exhaust_filter_grill.stl (Voron). Skip exhaust_filter_housing, [a]_exhaust_filter_mount_x2, [a]_filter_access_cover, [a]_exhaust_fan_grill. They come back only with the optional chamber exhaust fan (added 2026-10-03, Ch 14 Part H): an add-on print outside the plates, made after Step 14.25 has checked the machine — 101 g, 7.1 h in two jobs, slicer/addons/exhaust-voron2/.

Plate B10-P1 — all six black parts. 5.7 h, 76 g.

Notes: - The "2X" in the filenames means print two copies; each file contains one body. Cross-check against the mod's BOM: 6 split bushings and 4 M5×45 dowel pins = 2 door hinges + 2 handle hinges. - Hinge on the right / handle on the left? Mirror the two Hinge-L-* parts in the slicer; handle and latch are symmetric. (Clicky-Clack README) - Because you're fitting Clicky-Clack, do not print door_hinge_x6, handle_a_x2, handle_b_x2, latch_x2 (Voron), nor LDO's LDO Door/ set. That also means you lose the LDO kit-number nameplate — if you want it, print LDO Door/handle_b_nameplate.stl and glue it somewhere else. - Resolved (survey, 2026-09-05): the Clicky-Clack "Blue" option is the door's aluminium frame colour, matching the blue LDO frame — visible trim around the front opening, sitting with the blue accent parts and the black body.

Batch B11 — Bay ducting (PETG V0, outside the ASA run) · 5 plates · 25.0 h · 348 g Jet Black PETG V0¶

Unlocks: Electronics (p.148–173): Ch 09 fits two printed conduits in place of LDO's five PVC wire ducts; Ch 10 fits the strip fin. Layout v3, adopted 2026-09-23 — design record review/2026-09-23-bay-mods/layout-v3/layout-v3.md. Page: manual/print/B11-bay-ducting.md.

Not in any run total above or below. Prusament PETG V0 Jet Black on the textured sheet, sliced with slicer/bay-ducts-petg.ini (3 perimeters, 4/4 solid, 20 % grid, no supports: ducts carry no load, so not Voron spec). STLs: MyStoopidStuff's remix of RyanDam's Cable Management Duct (Printables 502306, GPL-3.0), stock pieces committed in slicer/stl/bayducts/mss/502306/ (the Printables model was withdrawn by 2026-10-18), remixes for the Rev D+ bay committed in slicer/stl/bayducts/remix/. The parts table with per-copy grams is on the batch page; per plate:

Plate B11-P1 (0.4 h, 4 g) — before kit, printed first and alone: V3L_COUPON_22N_DUCT + cover, the lid-snap test for the narrowed middle run.
Plate B11-P2 (6.9 h, 96 g) — before kit: DC front run (CMD_V3_1H_154mm_DUCT ×2 + covers) and the three 90° corners (CMD_V3_1H_90DEG ×2, V2L_90DEG_MIRROR, + covers).
Plate B11-P3 (4.6 h, 73 g) — before kit: the AC conduit (V3L_WIRE_BOX_PORT + plain lid, V3L_90DEG_R15 ×2, CMD_V3_1H_T_SHORT, endcaps ×2, + covers), V2L_STRIP_FIN, and the DC S-jog (CMD_Remix-V3_DUCT-2B_45deg ×2 + lids).
Plate B11-P4 (6.3 h, 82 g) — after the kit-day measurements: the custom lengths, V2L_58mm_DUCT ×3, V2L_130mm_DUCT, V2L_70mm_DUCT, V3L_10mm_DUCT ×3, V3L_34mm_DUCT_HOLE, + covers.
Plate B11-P5 (6.8 h, 93 g) — after the kit-day measurements, only if the Leviathan-to-PSU gap is ≥ 25 mm and the coupon passed: V3L_154N_DUCT ×2 and V3L_T_REG_N ×2, + covers. Otherwise the fallback, stock CMD_V3_1H_T_REG + one CMD_V3_1H_82mm_DUCT, with LDO's PVC middle duct kept.

Notes: - Before kit, 3 plates, 11.9 h, 173 g; after the kit-day measurements, 2 plates, 13.1 h, 175 g. - Kit-day confirmation: the v3 route adds ~195 mm to the A motor lead and ~129 mm to B. Either way, P4 and P5 print on schedule; a short lead gets a longer replacement (4-pin JST-XH) rather than a drop to layout v1. - All five arrangements are provisional (nest.py), GUI QC pending. - Options, no plate: orange-ASA endcaps; MSS's WARNING lid (Printables 505838) waits for the INDX.

4. Totals, margin, spool changes¶

4.1 How these numbers were produced¶

Every plate hour and gram in this document is a PrusaSlicer 2.9.6 estimate, produced by actually slicing the plate — not modelled. slicer/build_plates.py arranges each plate's real STLs on the 250 × 220 bed, applies the per-object brims, writes slicer/plates/<plate>.3mf, slices it and reads ; estimated printing time (normal mode) and ; total filament used [g] from the G-code footer. slicer/estimates.csv lists every plate beside the figure it replaced.

The configuration is the one in manual/print/00-slicer-setup.md: system presets 0.20mm STRUCTURAL @COREONE 0.4 / Prusament ASA @COREONE HF0.4 / Prusa CORE One HF0.4 nozzle, plus every override in that document — 4 perimeters, 5 solid top and bottom, 40 % grid, forced 0.4 mm extrusion width, shrinkage compensation zeroed, and the reduced speeds. Grams use the profile's own 1.07 g/cm³ ASA density.

What replaced what. The previous figures (134.3 h / 2248 g) came from a geometry-plus-throughput model: wall-and-skin volume × 1.03 overhead, time = volume ÷ 4.5 mm³/s. Sliced, the build is 157.0 h / 2092 g — +17 % time, −7 % filament. Both errors have the same root: the model assumed a flat 4.5 mm³/s, but the override table deliberately trades throughput for quality (perimeters 70 → 55 mm/s, external 50 → 35, first layer 45 → 25), and it over-counted material by treating 4 perimeters as a solid 1.6 mm wall where Arachne varies the beads. Every plate moved the same direction — the largest single change is B07-P1 at +2.2 h — so the shape of the plan (which plates are long, which are short, what to start in the morning) is unchanged.

Still calibrate on the first plate. These are estimates from a slicer, not measurements from a printer. Slicing slicer/plates/B00-P1.3mf yourself will return 3 h 58 m and 51.7 g to the minute, because it is the same file. What is worth measuring is the printer: record B00-P1's wall-clock time and the weight of what comes off the bed, and carry that ratio forward.

Cross-check against the community numbers: stripping the mods (the Klicky set ≈51 g, COB mounts 124 g, LDO extras) gives ≈ 0.95 kg functional and ≈ 0.90 kg cosmetic, against the widely-quoted ~1.0 kg / ~0.9 kg for a Voron 2.4 350 set. Total print time 157.0 h sits at the top of the commonly reported 120–160 h band — which is what a quality-biased profile is supposed to do.

4.2 Filament budget¶

PrusaSlicer 2.9.6 estimates. The old model said 1940 g black / 308 g blue; slicing gives 127 g and 29 g less — margin you gain, not a budget to spend.

	Needed	On hand	Margin	Reprint allowance
Galaxy Black	1813 g	2400 g (3 × 800 g)	587 g	32 %
ASA Blue	279 g	800 g (1 × 800 g)	521 g	187 %
Total	2092 g	3200 g	1108 g	—

Black margin is comfortable, but not unlimited. 587 g is about three of the largest plates. Typical first-build reprint rate is 10–15 %, so you should land fine — but:

Don't burn black on the optional extras (bed_hole_marking_template, bottom_panel_template, purge-bucket sheet stops, extra bestagon inserts) until the machine is standing.
If any single plate fails twice, order a fourth black spool that day rather than mid-B08.
If you do run short, the cheapest place to substitute is the skirts and panel clips — those see no heat and no load, and the Voron docs explicitly permit PLA/PETG there (materials page). Don't substitute anywhere else.

4.3 Spool changes¶

Cumulative black consumed after each batch: B00 52 · B01 353 · B03 472 · B04 589 · B05 667 · B06 815 · B07 1041 · B08 1440 · B09 1737 · B10 1813 g.

With 800 g spools and the numeric print order, spool #1 carries B00 through B05-P1 and ends with ~133 g. B06-P1 starts spool #2 on that stub rather than risk a resume seam: the plate holds the Revo hotend seat and the Clockwork 2 gear bores. #2 then runs to the end of B08-P4 with ~27 g left, and spool #3 takes over mid-plate inside B09-P1 — Nevermore plenum, plenum lid and cartridge lid, nothing dimension-critical, so the Core One+ runout sensor pausing and resuming there is fine. #3 finishes the build with ~454 g spare. Same fresh-spool rule as B06 applies to B01-P1 (the 15.2 h, 201 g plate): a resume seam on a Z-drive body is not worth the risk, so it wants ≥201 g on the spool at the start — it has 748 g. Record what is actually consumed in the spool ledger in manual/print/README.md; the prediction above is only as good as the first few weighings.

5. Orientation, brim, and per-batch checkpoints¶

5.1 Orientation and brim¶

Do not change which face sits on the bed. Every Voron, LDO, Klicky, Nevermore and Clicky-Clack STL ships pre-oriented for support-free printing. Rotating a part about Z (in the plane of the bed) to make it fit is fine — it does not change the layer orientation, and plate B08-P1 needs it (side_fan_support turned 90°). Two exceptions to the face rule:

XY_cable_chain_bridge-Igus-3mm_backer.stl is a community remix and arrives standing 44 mm tall on a 21 mm-wide footprint, unlike the stock part which lies flat. Check it in the preview before slicing — if it isn't sitting on a flat face, lay it down to match the stock [a]_xy_joint_cable_bridge_2hole.
Mirror the two Clicky-Clack Hinge-L-* parts if you want the door to swing the other way.

No part in this build exceeds 150 mm in Z. The tallest are, in order:

Part	Height	Footprint	Aspect	Action
`Handle.stl` (Clicky-Clack)	60.0 mm	67.9 × 18.6	tall & narrow	5 mm brim
`Latch.stl` (Clicky-Clack)	58.0 mm	25.9 × 14.6	very tall & narrow	5 mm brim
`Hinge-L-sleeve/solid-2X` ×4	55.0 mm	20.9 × 19.5	very tall & narrow	5 mm brim
`mount.stl` (TFT)	44.8 mm	117 × 67	fine	none
`z_motor_mount_a/b` ×4	42.0 mm	51 × 30.7	borderline	brim if you see any lift

Separately, brim the long flat parts — not because they're tall but because 150–182 mm of ASA on a plate lifts at the ends: 3 mm brim on rear_center_skirt_350, front_skirt_a/b_350, side_skirt_a/b_350, side_fan_support_x2, keystone_panel, power_inlet_IECGS_1mm, exhaust_cover, V2_Duo_Plenum, Regular_Cartridge, wago_221-415_mount_3by5, exhaust_filter_grill, cob_light_strip_mount_100mm. Brim separation stays at PrusaSlicer's 0.1 mm so it snaps off. (Prusa warping KB)

Parts with built-in supports to break out, not cut: [a]_stealthburner_main_body, Regular_Cartridge (Nevermore), V2_Duo_Plenum. The skirts are single-shell parts — they have no break-away body.

5.2 Checkpoint after each batch¶

After	Inspect	Most commonly reprinted here
B00	Gate A and Gate B in §1.4. Nothing proceeds until the rows you can run today pass; Gate B's bearing and rail rows sign off on kit day.	the cube, until the profile is right
B01	Each `z_drive_main` and `z_drive_retainer` 625-2RS pocket calipers 16.30 mm ±0.15 now; on kit day a real 625-2RS (16 mm OD) must thumb in with no rocking. M3 inserts wait for the kit's own (Step 02.04). Check the 4 mm/3 mm deck-support call.	`z_drive_main_*` — largest single parts, most exposed to warp at the corners
B02	Guidler and latch must move freely against the CW2 body once it exists (B06) — test-fit then, not now. Check the SB main body's built-in supports came out clean and the LED pockets are crisp.	`[a]_stealthburner_main_body` (most-photographed part in the build)
B03	The F695 flange seats caliper 15.00 mm now; on kit day the real F695-2RS (13 mm OD, flanged) bearing/spacer stacks must drop into them without reaming. Either way the two halves of each drive unit must close flat with no gap. (625-2RS is the Z-drive bearing — B01, not this batch.)	`a/b_drive_frame_lower` — the bearing seats are the tightest fit in the machine
B04	Test the MGN12 carriage screw pattern against `x_frame_V2TR_MGN12_*` before you commit heat-sets. XY joint bores must accept the shafts without reaming.	`xy_joint_*_lower_MGN12`
B05	Z joints: `z_joint_lower`'s four M3 holes caliper 3.4 mm on a 15 × 16 mm pattern; `z_joint_upper` must sit square on the extrusion.	`z_joint_lower_x4`
B06	Revo Voron hotend must sit flat in the printhead front with 4× M3×8. Klicky: magnets pressed below the plastic surface, polarity consistent, and the probe must attach/detach cleanly from the AB mount.	`KlickyProbe_v2` (that's why you print two)
B07	Wago mount heat-sets; COB mount halves must close flush on their 2× M3×6 FHCS.	`cob_light_strip_mount_100mm` (warps at the ends — check flatness on glass)
B08	Lay every skirt segment on a flat reference (your granite counter) and check for rocking. A bowed skirt is the most visible defect on a finished Voron. Also dry-fit the ring: front + TFT mount + front, rear + inlet + keystone, sides + fan supports.	`rear_center_skirt_350` (182 mm — the worst warp candidate in the set)
B09	Panel clips: snap one onto an extrusion with a 3 mm offcut to confirm 4 mm vs 6 mm choice before printing all 31. Nevermore: plenum lid must slide in its groove; cartridge must snap onto the plenum.	the 6 mm corner clips, if the foam tape choice changes
B10	Sleeve bearings must tap into the hinge sleeves without splitting the part; M5×45 pin into the "solid" half should be a very tight hammer fit with ~20 mm proud.	`Hinge-L-solid-2X` (split risk on the pin press)

Across the whole build, the three parts most often reprinted by Voron builders are the A/B drive frames (bearing fit), the long skirts (warp), and the Stealthburner main body (cosmetics). Budget your 587 g of black margin against those.

6. Conditional / verify items¶

Item	Status	What to do
Deck support thickness	LDO's guide says 4 mm, LDO's 350 BOM says the deck panel is 3 mm	Print `deck_support_3mm_x8` ×8 now (the size-specific BOM wins); measure the panel on arrival; 8 g to reprint at 4 mm
`PSU_stabilizer_50mm`	LDO says "SKIP p.169 — no support bracket"	Print it (4 g), fit only if the PSU needs it
Probe retainer bracket	8 mm vs 9 mm probe barrel	Measure the Omron on arrival; the `_9mm` variant is 0.5 g
Cable-chain bridge with Ti backers	Fabreeko's backers ship pre-drilled with pilot holes for the cable-chain end link (drill 2.5 mm, tap M3 to use them), which may make the printed bridge unnecessary; the backer-aware remix exists in 3 mm and 6.5 mm	Both the stock `[a]_xy_joint_cable_bridge_2hole` and `XY_cable_chain_bridge-Igus-3mm_backer` are on plate B02-P3 (18 g total). Fit whichever clears. "Igus" = the 2-hole chain pattern, which is what LDO ships.
Keystone blanks	Panel has 2 slots; LDO supplies 1 CAT6 keystone	1 blank used, 1 spare — both on B02-P3
Clicky-Clack "Blue"	Fabreeko doesn't state what the colour governs	Ask before it ships
Rev D+ printed-parts guide	Doesn't exist; only Rev A/B, C, D	Resolved: D+ changes one printed part (§0). The remaining Discord question is only whether a D+ guide will be published.
`mount.stl` vs `mount_thick.stl`	LDO links the folder, not a file	`mount.stl` chosen (30 g vs 74 g); swap if you want brightness-button access

Optional, not in any batch (print later if you want them): bed_hole_marking_template_x1_Rev2 (LDO's bed is pre-drilled), bottom_panel_template, Purge Bucket/brush_holder_sheet_stop + individual_sheet_stop (superseded 2026-10-03: the nozzle scrubber is jinetix's silicone-wiper design with sheet stops, Printables 796563, an add-on outside the plates, never printed ahead of kit day: Ch 13 Part L measures the machine, slicer/addons/scrubber-796563/remix.py generates the parts from those numbers (or says no-go), and only then are they printed — about 3 parts, 38 g black ASA, 2 h 30 m; the kit's brass brush is a hand tool), [a]_fan_grill_open_optional_x2, z_belt_cover_a_led (LDO variant if you route the LED strip through the Z-belt opening), extra ldo_bestagon_inserts.

7. Deliberately NOT printed¶

File	Why
`nozzle_probe.stl` (Voron) and `nozzle_probe_ldo.stl` (LDO)	LDO supplies the nozzle probe printed
`Leviathan_bracket_set.stl`	Supplied printed (L + R)
`usb_adapter_mount` base body	Supplied printed (the file is still printed — for a spare base; the Nitehawk-SB V2 partial cover replaces its cover body)
`bed_wago_mount.stl`	Supplied printed
`led_fan_pcb_spacer_x2.stl`	Supplied printed (×2)
`[a]_pcb_spacer.stl` (CW2)	Supplied printed — printing a spare anyway, 0.3 g
`cw2_chain_anchor_tilted.stl`	Supplied printed
`[c]_stealthburner_LED_diffuser.stl`	Supplied printed in clear PETG; you have no clear filament
`[a]_endstop_pod_hall_effect.stl`, `z_joint_upper_hall_effect.stl`	No hall-effect endstops in this kit
`Octopus_bracket_set.stl` and all other `Controller_Mounts/*`	Leviathan, not Octopus
`raspberrypi_bracket.stl`, `beefy_raspberry_bracket.stl`	Leviathan has an integrated Pi mount (Rev D)
`rs25_psu_bracket.stl`	No 5 V PSU in this kit
`mini12864_case_front/rear`, `[a]_mini12864_case_hinge`, `[a]_mini12864_case_front_insert`, `[a]_btt_knob_light_shield`	BTT touchscreen replaces the mini12864 module
`exhaust_filter_housing`, `[a]_exhaust_filter_mount_x2`, `[a]_filter_access_cover`, `[a]_exhaust_fan_grill`	Nevermore replaces the stock exhaust filter; kit has no fan for it. Printed later only for the optional Ch 14 Part H exhaust fan, outside every batch
`door_hinge_x6`, `handle_a_x2`, `handle_b_x2`, `latch_x2`, LDO `LDO Door/*`	Clicky-Clack replaces the stock doors
`power_inlet_IECGS_1.2mm`, `power_inlet_filtered`, `plug_panel_1.2mm`	Kit ships the 1.0 mm inlet
`xy_joint__MGN9`, `x_carriage__MGN9`, `[a]_belt_clamp_MGN9_x2` (Superceded)	X axis is MGN12
`zipchain2_*` (Superceded)	Kit ships real drag chain
`[a]_z_tensioner_x4_6mm` (Superceded)	Kit ships 9 mm-wide Z idlers
`pinda_adapter`, `chain_anchor_3hole`, `cable_door.stl`, `Bowden/`, `ADXL345_Mounts/*`	Wrong variant for this kit
`deck_support_4mm_x8`, `probe_retainer_bracket_9mm`	Conditional, not excluded — the caliper decides (§6). `deck_support_3mm_x8` is the printed default (Rev D 350 BOM); the 4 mm set is the reprint if the panel measures 4 mm.
`spool_holder`/`bowden_retainer` — these ARE printed (B09)	listed here only to avoid confusion with Spool_Management's other files
Beacon, Nevermore StealthMax, StealthChanger parts	Explicitly out of scope for this build

8. Where to do the Core One+ Gen 2 belt upgrade¶

Where things stand (2026-09-23). The Core One+ is built and commissioned — commissioning closed 2026-09-13 on Gen 1 (GT2) belts, bed flat to ±0.1 mm on printed Z-stop correction caps. The Gen 1 → Gen 2 upgrade kit (Prusa order 1787919456) has shipped. The LDO Voron kit has not: realistic delivery is late November to late December 2026.

Decision (2026-09-23): deferred to the INDX rebuild, this winter. The Gen 2 upgrade is no longer done before B00. It installs together with the INDX 8-tool conversion — Prusa documents the combined job (https://help.prusa3d.com/article/assemblling-the-prusa-indx-core-one-with-the-gen-2-upgrade_1147602). The whole 157.0 h / 22-plate run — B00 → B10, numeric order — prints on the current Gen 1 GT2 belts. This supersedes the earlier "Gen 2 before B00" baseline and its 2026-10-15 contingency; the mid-run pause is retired, because nothing changes the machine under the parts.

Why. The printer is commissioned and printing well; the upgrade fixes neither open issue on the bench (loadcell/heater noise, PETG infill strands); a heatbed swap now risks the closed bed calibration and forces a belt retune, XY-homing recal and a start-G-code re-sync of all 22 committed .3mf projects; GT1.5's only benefit (less VFA) is cosmetic, and Galaxy Black's metallic fleck already hides it; one teardown, with INDX, beats two.

Two checks replace the upgrade, before B00 — full tick list at 00-slicer-setup § Gen 2 belt upgrade and B00 § Before B00 checks, both (verify on bench):

Belt pluck check — belt tuning was never formally closed. Targets upper ≈96 Hz, lower ≈92 Hz, ≤8 Hz apart; out of range, retension via Control → Calibrations & Tests → Belt Tuning.
Hot first-layer check, at ASA bed temperature — the bed has only been verified flat at 60 °C. It runs after Step B00.0's wizard, on the committed project slicer/checks/hot-first-layer.3mf: five 30×30×0.2 mm squares, corners + centre, one layer, in Galaxy Black ASA on B00-P1's presets (110 °C bed, cold start G-code); pass with no Z-alignment prompt, 0.17–0.23 mm each, spread ≤0.05 mm.

Revised 2026-10-01: expansion joints and nozzle wiper before B00, belts at the INDX rebuild. The heatbed expansion joints and the nozzle wiper from the same kit are fitted before the two checks; the GT1.5 belts and pulleys still wait for INDX, so the run stays on GT2. The firmware switches for the joints and the wiper are set one by one (Edition = Gen 2 would also set GT1.5 steps/mm), the bed is re-checked to ±0.1 mm because the heatbed came off, and the hot check runs on both start G-codes (cold, and heat-then-off) to pick the one all 22 plates carry. Tick list: B00 § Before B00 checks.

After the eventual INDX + GT1.5 belt rebuild, before restarting prints:

Firmware ≥ 6.8.1 (carries GT1.5 belt support and the Gen 2 expansion joints).
Re-tension both belts and re-square the gantry, per the combined INDX + Gen 2 guide.
Re-run the self-test and input shaper calibration.
Re-print Voron_Design_Cube_v7 and re-pass Gate A (§1.4) — steps/mm changes with the pulleys, so the dimensional gate has to be re-passed before printing on the rebuilt machine. Judge its first layer per §1.4 step 3; the loadcell re-zeroes on its own and there is no wizard to redo.

Do not try to interleave a belt/tool upgrade with a running plate; the Nextruder and bed have to come apart.

9. Machine-readable batch summary¶

Hours and grams are PrusaSlicer 2.9.6 estimates sliced from slicer/plates/*.3mf (§4.1); per-plate detail with the previous model figure beside each one is in slicer/estimates.csv.

hard_prereq_batches = batches that must be printed before the assembly chapter in unlocks_chapter can actually be completed (B00 is the calibration gate for everything; B02 carries the accent parts that most mechanical chapters need).
