HID iClass SE RKLB40 backbox

I needed a surface mount backbox for an HID iClass SE RKLB40 fingerprint/prox reader for an install that I couldn't put a cut-in box in so I modeled this. I'm going to drill a small hole in the side and run a bit of wire-mold to it but in the interest of maybe helping out the next guy I put mounting holes for single gang, double-gang, or directly to a 4-square depending on which screw hole you open up.
