Pinion gear holder for eight pinion gears. Slots to tighten the set screw so the gears won't come off. I used PLA on a QIDI Plus, all settings at default. I used Blender to create this model.
update 2/21 - uploaded reworked model which uses M3 16mm screws (Thanks Malcolm). I've added the tooth numbers with one blank. The tooth numbers I have are used in a associated B6.2 outdoor carpet buggy and may not be the best numbers for you application. When I printed this some of the screw holes we almost to large and I used a drop of glue on the underside to secure the screws.
Update 5/2/2024
Had a request for a 33 tooth gear(thanks Duane). I created a new model with, hopefully, holes big enough for a 33 tooth pinion. I didn't include sizes for the new model as you can use a fine tipped magic marker to label the gear sizes.
The author marked this model as their own original creation.
