This is a replacement gear for the large black carriage gear inside an original A9M0337 Apple Scanner. These gears tend to have broken teeth which cause the scanner to not function.
Remove the old gear and clean the spindle well with alcohol as it's likely sticky causing too much friction. The small donut goes on the post first and raises the gear above the motor screw below. The gear goes on next. I reused the small cap and retaining circlamp to secure the new gear on top.
The teeth on this model (144 teeth on the outside) are very tiny. I wasn't sure if it would, but I tried it on a Bambu P1S with a 0.2 nozzle and 0.1 layer height with reasonable success. Not sure how long it will hold up but it feels stronger than the old gear so it's a start.
I still need to examine the scans to see if they are good. The other issue is the gear makes an oscillating sound when the printer moves at high speed. My guess is this may be because my prints aren't perfectly square. More testing needed.
