Ikea shelf mount

I lost some of the Ikea shelf mounts during a house move. I printed this replacement. I tested one to destruction and it took a large chunk of my full weight on it before it broke but you should not expect it to be remotely as strong as the metal ones that I was replacing.

For acceptable strength you will want to print it in the orientation in the STL with supports so the filament direction is along the length. Should already be all edges given the size.
