It works! It's a rock tumbler polisher! Yay! I printed this in resin. Make sure the holes are supported well. The need to be true to accept the bearings. You'll need 4 22od x 8id mm bearings. You'll need a motor too. The drive gear is 0.5 module. It's a small tooth common to a lot of printer motors. Speaking of motor, it's a used printer motor that can run for hours off a 9v battery.
