Wall mount for Ikea STYRBAR (E2001/E2002)

I designed this to wall-mount my Ikea STYRBAR remote for the TRADFRI living room lights and make it sort of match the other light switches and outlets. To mount on the wall, mark out and install two or four diagonal screws at 94mm spacing (two are easily enough). Place the cover over them and rotate counter-clockwise to affix. Rotate clockwise to release. To install the STYRBAR inside, glue in the metal backplate with glue or double-sided tape, then magnet the remote in place as normal. Magnet mounting allows for easy removal to swap batteries.
