I made this switch plate cover to match the Control Panel I just released. It uses standard wall rocker switches. and replaces or goes over the top of a standard cover plate. I designed two types, one type leaves the switch exposed and the other hides the switch behind a set of push buttons.

There are two button styles, they are both interchangeable. There is a taller easier to press version, and a lower profile version with shorter, smaller buttons. There is a round, hex, and rectangular button shape for each style.

There are 1 and 2 gang versions of the switch plate, and 1, 2, 3, and 4 gang versions of the push button back plate. There are two different versions of each type of plate. The standard version will replace the switch plate, and the “cover plate” version will go over a standard switch plate cover. I recommend using the “cover plate” version because it is the safe option as a 3D printed PLA cover plate is not CE or UL rated.

The downsides are that the plate is slightly thicker, and the cutout for the cover will require supports. The supports won’t be seen once its mounted and they are pretty easy to remove so its just some waisted filament. The back plates are split into two different stl’s for a multi-color printer. The stl’s can be joined for single color, or you can do a manual filament swap at the layer height where the screw heads start for a dual color print.

The mounting screws for the switch hold the button bezel to the back plate, and the back plate to the wall. The buttons are trapped between the bezel and the back plate. They utilize the standard #6-32 screws, but they will need to be longer than standard. I suggest using a 1” long screw but I found it cheaper to buy this wall plate screw assortment, then a single length.
