Bearings with 6mm BB bullets(6mmのBB弾でベアリング)

thingiverse

The bearings are made from 6mm BB bullets. I measured the diameter of the BB bullet with a caliper and it was about 5.9mm. https://github.com/takeru/BBBallBearingGenerator I set the size of each part with this generator and generated it with Fusion360. dbb=6.0 is too tight. dbb=6.5 is too loose, When dbb=6.2, it's a little bumpy, but it goes around and around When dbb=6.1, there's no clatter, but it's a little hard to turn DBB=6.1 or 6.2 seems to be just fine.
