Ball-Bearings
thingiverse
Designed a Ball-Bearing utilizing 6mm/4,5mm Airsoft BBs. It is easy to assemble thanks to the recess on the side. It's small enough so that no BBs fall out. It should work right after printing. If the Bearing doesn't spin smoothly try sanding the inner surface, especially at the Z Seam. Preferably use high quality seamless BBs. Steel BBs should increase the longevity of the Bearing.
