Challenge Coin Wall Mount

This is a wall mount for (fairly) standard 50mm diameter x 4mm thickness challenge coin, such as the ones issued by Radiotopia and the 99% Invisible podcast! I wanted to be able to fix them to the indie of wall-mounted display boxes.

I went through several iterations, and this model strikes a balance between the ease of clipping coins in and a snug fit. It should be reasonably tolerant of small differences in coin thickness, and has a raised brace behind the centre of the coin to keep it pushed against the front clips.

The holder has a countersunk hole in the centre for a standard 4mm screw with a 6mm Philips head.
