This is a snapping pivot hinge. It does not have a pin or screw. I intend those to be metal hardware. A nail can be used as a pin to keep the two parts together. The rail can be attached to what you want to hinge together. Then slide the SNAP-HINGE in place and screw/ rivet/ bolt it into place. Connect the two parts of the hinge with the pin you choose. Now connect the other side of the hinge to the opposing part. The Current size is 50.50 x 13.59 x 34.96 mm I designed this hinge specifically for another project I'm working on. Follow the link to see what else I'm working on.

I recommend this be printed with solid infill. This should hold 2-3 lbs. Weight will change based on size and filament used and scale at which you print this. Can be printed in PAL, Nylon, or anything else. Use your best judgement when using it for your own projects.
