90 degree corner clamping jig

thingiverse

I needed a way to hold two wooden parts firmly and squarely at 90 degrees to each other. There's plenty of good corner clamps around already, but I only needed a simple and quick jig that I could use with an existing clamp. To use, just put on the inside and outside of the corner joint and you'll have two parallel surfaces to clamp together. Any material should be fine. Print with more walls for strength and rigidity. Minor edit, increased inner corner relief chamfer and added edge chamfers to make it less sensitive to printer settings
