Just a standard light switch plate/cover.

Print instructions

Print at 0.25mm(best for color switching) with the hexagon design laying flat on the build plate (no supports). If you want a dual-color design, use MMU or switch filament at 0.5mm. In my case, I had two layers of PolyAlchemy Elixir Nighshade PLA, and the rest was generic black PLA.

I attached a STEP file, but that's probably not too useful for anyone... Go get your own dimensions if you need them--mine are probably a bit off.
