Tradfri switch holder
thingiverse
Ikea Tradfri (Trådfri) light switch & Shortcut button holder. That fits the Skadis (skådis) "peg bord" There seems to be two versions of the metal backplate, they changed the "slot hole" it should fit both. Its purposely made quite thin to hide behind the plate instead of the sticky tape that comes with it. Superglue it on and it will be flush with the skadis board.
