Corner Clamp

thingiverse

These custom corner clamps make it easy to join boards like foam, hardboard, or even cardboard into a box shape. To assemble each corner, print two of them, then run a nut and bolt through the hole - you're ready to go. I created these for my I3+ printer enclosure project, opting to build one instead of buying an Ikea table. The elevated design was added to allow heat to escape from the main printer body and electronics, which were getting too hot. This simple modification solved the problem.
