This is an enclosure for Xiaomi Aqara light switches. It features a 4-screw design that allows to remove the switch from the box without the risk of breaking the plastic latches.
The standoffs have some support material integrated and can be easily removed. The screws hold them in place.
The solvespace design file is provided, so you can add any needed holes for wiring before actual print.
