Playstation button icons color lamp
thingiverse
Yet another PlayStation button lamp. I managed to minimize the non-uniformity of the light emitted by the LED. To achieve this, the parts name *_sep.stl was carefully chosen. They were generated by taking a picture of the diffusion and translating it into a height map. The parts [triangle, cross, circle, square] are printed in transparent for the first 1.2 mm before switching to black. Then, the inside is painted white to enhance light diffusion. The front transparent layer is sanded down. *_sep.stl was printed in transparent. *_cap.stl was printed in black. To fill with your favorite "neo pixel" and Arduino flavor, I used SK6812 RGBW LEDs with an ESP32.
