While building a case for my Orca, I realized, that it would be nice, to cover the corners of the wooden box. So I designed these box corners.
There are 3 variations, use the one with 0 holes, if you want to glue the corners, or use the versons with the holes, to screw them in place.
Just print them, no support needed. I recommend printing them with 100% infill. Because the walls are only 2mm thick.
