recessed outlet

Ever been in need of a recessed outlet? Maybe behind a mirror to plug in it's light?This may be the solution for it.I had to come up with a concept for a customer who wouldn't wanna see any cords around it's lighted mirror.There is enough room to fit a stiff 3 prong plug in its 120v receptacle. Just install the receptacle in a 4x2 steel electrical box and mount it with the original white screws onto the hidenoutlet.I used M3x40 screws with 2 nuts to stop the M3 from moving around.Cut a hole of 10.5cm wide and 11cm high into the drywall insert this contraption and tighten up the tabs.Print in ABS preferred.
