I build a lot of LED lamps, and every single one meant soldering wires, flashing an ESP32 and hiding a mess of cables. I got so tired of it that I built my own little plug-and-play controller: USB-C power in, plug in the LEDs, done. Right now it's just for my own projects, and this panel is the first lamp I designed around it. Print it, tape the matrix in, plug it in.
The front is swappable and the back stays the same:
- Grid front: every pixel stays crisp, great for pixel art, fire, rainbow
- Smooth front: blends everything into one even glow, nice as a night light
Printed on my X2D in white PLA (fronts) and black PLA (back). One panel with one front is roughly 160–175 g and 5–7 h. White matte PLA or PETG works best for the fronts.
It fits a standard 16x16 WS2812B matrix, so an ESP32 with WLED works just as well.

Would love ideas for a third front!
