Do:

  1. Sort the drive parts into *_a and *_b piles, two drives each, against the pair renders above.
  2. Write a or b on the inside face of every part.
  3. Reject any part with a lifted corner or a delaminated bolt boss.

check Check

12 black parts: 4 main, 4 retainer, 4 motor mount, two of each hand; 8 blue accents, 4 idler brackets, 4 sliders, 8 deck clips.

helperHelper Sorts the printed parts into the a and b piles and counts them.

What you're looking at

The printed parts from three batches: the deep z_drive_main body and shallow z_drive_retainer tray that clamp each drive's bearings, the motor mount L-brackets, the blue baseplates and belt tensioners, and the Z idler brackets. Every one exists as a mirrored _a and _b.

tip Tip

Cradles up: the z_drive_main cut corner and its two 9 mm bolt wells sit far from you on _a, near on _b. The retainer cut corner is near-left on _a.

tip Tip

reprint rather than force a warped z_drive_main — it holds the shaft alignment for the whole Z axis. src
