My wall sconce originally came with clear glass tea light cups. I wanted something a little more unique, and something that would diffuse the light better, so I replaced them with 3d printed cups.

I printed them in glow in the dark PLA. This PLA has a beautiful rainbowy sheen when you shine light through it, and of course it glows softly for a while after I turn the lights off. Lovely.
