Printing this object will allow you to measure surface roughness as affected by X/Y backlash, and Z wobble. Instructions I recommend that it be printed using black filament, as it really brings out the defects. I will be working on a RoboRealm sketch that can process images of the part, and calculate some kind of roughness value.
