Ribbon Cam lock

Here is a 20mm Ribbon Cam lock.

Requires a 3x30mm Bolt
3mm Nut 8-)
Calibrated printer

I used ABS
245 head
105 bed, then drop to 99 after 2 layers with krypton tape
Print 2 layers, heavy infill and 0.2mm layers or less

The base is shown the correct way to print (Smaller U shape edge to the bed), but the cam needs to be spun, and put the hole side on the bed. (See Photo)
