How did you make it? Did you 3D print?
Nope! Just a basic puck light, with a clear ring from another larger, scrap puck light, a shower flange, washer, and a large clear bead.
I went over the clear cover on the puck light with a blue Sharpie to give it the proper blue look, and glued the washer over the larger hole on the flange, and glued the bead over the smaller hole in the washer. I covered the bead with some painter's tape, and spray painted it with some flat black primer, and carefully went over that with a light coat of bright coat aluminum paint, to give it a slightly anodized look (I did the same to the outer casing of the puck light). Then, I just glued to together!
I don't actually have a 3D printer, but I've been meaning to get one. Space is just a bit of an issue. I'm already working on a better version of this, as this was just a quick prototype!
