Cutting Board Wall Mount

I made some pretty cutting boards and it seemed a shame to put them in drawers (and one was too big for any of our drawers) so designed these mounts to hang them on the wall in a way they could be quickly removed but were quite secure.

These were designed for cutting boards made of 4/4 wood (after finishing about 7/8" or 20mm thick) but should be able to be adjusted for any thickness you want.
