Simple corner clamp I designed for assembling acrylic boxes. Uses a m4 bolt/nut (I use the nylon thumbscrews and metal nut) and allows the panels to be put together without moving in order to adhere the seams.

My print settings but could use pretty much whatever settings you typically print with as it's not a complicated design.

P1S:

.06 Nozzle

.3 Layer Height

25% infill

Adaptive Cubic Infill Pattern
