Ball Bearing model for 3D Printing

I spent about fifty hours to create this ball bearing using the highest precision Blender offers (0.001 mm.)
I had worked through the Precision Modeling by Robert Burke (www.rab3d.com) for three days.

Classic modeling tutorial. Nice work!

Burke’s tutorial is awesome. Nice job making it to the end. Now all we need is better parametric tools, so it doesn’t take three days. ha
