The only post processing that needs to be done on the parts prior to assembly (inner race, outer race, and ball cage) is polishing the surfaces and cleaning up any printing artifacts.

Pre and post processing on the races and ball cage:

Assembly

The only assembly steps after post processing are:

1. To slide the ball cage and outer race over the inner race and then rotate the outer race so the ball cage is aligned with the indents on the outer race.
2. Place a 1/8in steel ball in the indent and press into place with a tool (takes quite a bit of force), repeat 100x
3. Greace the bearing and its ready to be broken in
