Full Graphic Smart Controller Case Wall Mount

I wanted a wall mounted clip so I could attach, the awesome looking, Full Graphic Smart Controller Case ( https://www.thingiverse.com/thing:1562144 ) to a wall when not in use.

The holes are 8 mm in front and 4 mm in the back.

It sits really well in just one clip, but I guess you could use two side-by-side if you feel the need.
