Category: Parts Summary

Bring Your Own Balls Parametric Bearing. I used 6mm soft air ammo for the bearings in the stl files but I have include the parametric Fusion 360 file so you can use whatever balls you have.

There are two versions of a 10mm I.D, 30mm O.D, 10mm thick bearing. The more spin version has more play between the balls and the races and spins for about three seconds when spun by hand. The less play version only spins for about a second but the inner race doesn't move around as much.

Both are made of three parts, an outer race, and a two part inner race that press fits together. The inner race parts could be glued together if needed but I haven't found it necessary.

EDIT: After dropping one and it popping apart I would recommend carefully gluing the inner race together. Try not to glue your balls together!

To assemble put the bottom inner race on a flat surface with the outer race around it. Lift up the outer race a bit to provide clearance for the balls. Once the balls are in position lower the outer race and put the inner race top on top of the bottom and push together. The included bearings take ten balls each.
