608 Bearing cap with thumb screw

This is a remix of http://www.thingiverse.com/thing:1988435

I changed one of the caps to have a dip opening where thumb (or other fingertip) can anchor when doing fidget spinner tricks. The originals were both flat.

Round_Cap_2.stl = the original one side
Round_Cap_1_with_thumb.stl = modified version of the original round_cap_1.stl.
