Summary

I had some rolls of solder that needed a home. This is meant for rolls that are 2.5 inches (63 mm) in diameter and 2.2 inches (56 mm) long. It uses two 1/4-20 nuts and two 1/4-20 x 1 inch long bolts. You press the nuts into the two inserts and screw the two bolts into the nuts to act as the axle for the assembly. You don't need to tighent the bolts in, but you can if you want them to provide some rolling resistance. When printing, you will need two inserts and one base.
