Badge Outlet Cover

I printed smitywa's Cop Badge Outlet Cover (https://www.thingiverse.com/thing:1726730) for my son's room. I did not notice until it started printing that it was not cut out in the back, and that the screw hole was not chamfered. I designed my own version with the cutout so it will fit flat to the wall, as well as chamfering the screw hole so it is more flush with the surface.
