Needed a few corner clamps for a box I'm making to hold the corners straight while the glue dries. I figured if I needed this then someone else might too, so here it is!

BTW I tried a couple of other designs but they didn't work very well or were fiddly to use and needed additional hardware.

The design is based on a G-clamp that I've seen before, but made from scratch.

I've provided the Buildplate in the right printing orientation. The only sketchy bit is the top of the threads on the base - a fair overhang there, but it printed fine for me with no supports.

NOTE: It's a good idea to increase the infill on the lower 5mm to decrease flex that can happen if you overtighten it.
