Frankenstein Lightswitch Plate (2022 Version)

Igor, throw the switch!

Yes, Master.

----------

I originally designed this seven years ago, and figured it's high time I made some long needed cosmetic updates: The blade portion is now symmetrical in both the ON and OFF positions, the knob prints as a separate completely round piece that snaps onto the end of the blade, I eliminated my own funky built-in supports for the switchplate (just turn on your slicer's supports for this part only), and the nubbin prints flat on its side without supports.  Lastly, I've included the STEP file for the assembly for people to remix for different non-US style light switches.
