I live in an apartment so I don't want to mess with removing the paddle switch so I designed this to replace the decorative plate and simply install over the paddle switch. No need to mess with electrical wiring.
Update 9/13/22:
Slimmed down the original version to look less boxy
Added two new versions: side mount next to a single switch, and dual switch covers
Installation:
Remove the decorative cover panel that's around your switch.
Use the existing screws to install this cover mount around the switch. (Ensure switch is set to ON position before covering it up)
Screw on the Lutron Aurora base over the toggle.
Snap in the Aurora button to the base.
Print Settings:
PLA, 0.3mm layer height, Supports enabled, gyroid infill @ 15%
