Rack Bolt Thread Test Kit
Description:
This is a 3d printed plastic bracket. It has a slot for cage nuts to be slid in from the side and holes for their corresponding bolts to secure them in place.
It was designed to hold one of each common rack bolt size/threading that I come into contact with: 12#24, 10#32, M5 and M6 to form a size/threading test kit.
