Summary

I needed a corner clamp to hold some parts in place while I glued them. I didn't have one, so I made this thing!
it's good for holding components up to about 4mm thick, it's a little bit fiddly, but I am reasonably happy with it.

Instructions

You need to print 1 No. 'clamp base.stl' and 2 No. 'plate.stl'
You will also need a couple of M3 screws and M3 nuts.
The inside of the pillars with the screw holes has a cutaway for a nut on the inner face. I put a screw in the hole, thread the nut on the end and use the screw to (gently-ish!) pull the nut into place in the recess. one of the points on the nut needs to be pointing up while you do this I finish up with a dab of super-glue on the edge of the nut, just to keep it in place.
repeat for the other side and bob's your uncle!
Please let me know if there are any problems making this, I'll do what I can to sort them out.
