This wall lamp prints in four colors. It's only 12 color swaps, so waste is minimal plus it's not insurmountable to print this on a single color printer with manual swaps. Add an LED puck light to the inside and you're ready to go. The cord channel is extra large to allow you to pass a USB cable and any external buttons through. It's light enough to hang with command strips or double sided tape, but includes a screw hole if you prefer to mount it that way.

I like it with a color changing light. You get some interesting effects when you change the light color. The 3MF prints each layer starting from the darkest color and ending with the lightest. I recommend keeping this order if you change the profile or colors. I had some nozzle travel bleeding/artifacts if I tried to print darker colors after lighter ones.
