Turntable

Adjusted for a larger bearing I just happen to have an excess of.

These now fit a [6201zz bearing](https://amzn.to/3BIpuh3)

12mm id
10mm wide
32mm od

These are a deep groove bearing, so as long as your tolerances are good, will support itself well. I allowed some gap fit in the tolerance, so you should be able to install then use a glue or a thin piece of paper if needed to keep it in place.

matches up to [this bearing I uploaded for testing](https://www.thingiverse.com/thing:6168256), but I would not recommend actually printing that and thinking it would spin.
