mini-clamp

A small clamp/vice using 1/4 20 @ 2" bolts.

you can install a small spring in the middle or glue the bolt into the bottom half

I designed these for a specific project that i needed to clamp along an edge of 3/4" material. If you want to clamp narrower materials. just print small spacer blocks to fill the opening to match your project.

probably possible to rescale it to fit other bolts
