I needed a very simple box for standard 20 mm switch, to be used for controlling LED lights. The box will be just glued to the corner of a desk, so I needed something small and not much fancy.

Print two SwitchBox_side.stl and one each of SwitchBox_front.stl and SwitchBox_back.stl. Or just use SwitchBox_all.stl.

Assemble the parts. They are made to just snap together. You can use superglue, hot glue or acetone (when printing from ABS) to glue them together, but it's not really necessary.

Put the switch to front and lead wires trough the back. If you want to permanently solder the wires, instead of using the crimping connectors, do not forget to feed the wires trough the front part first!
