I wanted to cover my existing light switches so they was not accidentally switched off and also have somewhere to place the Trådfri remote control. By mounting the remote recessed in the cover, it stays properly in place when pushing the buttons.

If access to the regular switches is needed, it is easy to remove the cover temporarily.

Print the cover upside down to get a smooth front surface. Place supports in the hole for the remote. The normal mounting plate for the remote is attached with double-sided tape.
