IKEA Trådfri holder

thingiverse

Square Trådfri on/off switches have magnets and metal plates which are fixed to the wall. - The magnets are quite weak and switches are easily dislodged. Thus, a holder for the switch (with a magnet) with additional walls to keep the switch still. I glued a magnet to back of the holder and used double sided tape to fix it on the wall. Circular magnets are from aliexpress, 12mm x 1.8mm
