notice that in the females face there is a line, left side is lighter because it is deeper.
it cost me $35 to order 10 her bearings. not to bad, just bad timing. I used artcam to make the relief. My desktop cnc machine has a wolfgang engineering spindle and I used a 1/16th ballnose endmill. Smallest I had that would cut this material as most of what I do is wax.
Here is one I did a while back in purple wax. The 15 degree .005 in tip cutters I use for wax I dont think will cut the white plastic.
