Tap to enlarge
Parts:
- M5×30 BHCS ×2 · Fasteners, Tools & Misc box
- black M5 washer ×2 · Fasteners, Tools & Misc box
Do: Turn the X assembly over and run an M5×30 BHCS with a washer under its head up into each of the single M5 T-nuts from Step 05.36. Light tightening again: the joint stays slightly loose until Ch 06.
Check
Two M5×30 in with black washers under the heads, both lightly tightened.
What you're looking at
Two more bolts, this time up into the joints from underneath the beam, each with a black washer to spread the load across the plastic. Pulled from both faces the joint cannot rock, but stays lightly tightened until squaring.
Caution
Rev D+ / LDO (p.104): "Use the black M5 Washer instead of the M5 Shim cause it looks nicer." This page is the documented exception to the precision-spacer substitution. src
