The file 'Turntable 3D Printer Model' is (3dm,stl) file type, size is 7.1MB.
Adjusted for a larger bearing I just happen to have an excess of.
These now fit a 6201zz bearing
12mm id
10mm wide

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, but I would not recommend actually printing that and thinking it would spin.
