Do you want a way to make sure light switches are in the "off" position? Do you want your room to look like a missile command room? Do you want to accidentally avoid turning on a switch?

If any of these are true (or even if they aren't), you can also print a cover for your standard US wall light toggle switch!

(Couldn't get the other models I found to work smoothly, so designed my own from scratch.)

The pieces are "press fit" (carefully) and require no additional hardware. For the best success, align one side into the hole, and then press in the other side from "the top" (aka the tip/center of the curve) -- this seems like the easiest/safest place.

[2022-02-02] Added "SmallerNubs" version; made the nubs slightly smaller to maybe allow them to slot in easier.

[2022-02-02] Added "PiP_untested" version; realigned the model (and increased the gap between the top of cover and the base) to allow for printing-in-place. Print with plate support!

[2022-02-02] Added "Lock" version; removes the doogit that switches the switch off, so you can have a "allow on" cover.
