Playstation button icons color lamp

Yet another playstation button lamp. I tried to mitigate the non-uniformity of the light emitted by the led. Thus the aim of the parts name *_sep.stl.
They were generated by taking a picture of the diffusion and translated to height map.

The parts [triangle, cross, circle, square] are printed in transparent for the first 1.2 mm then switch to black. Then the inside is painted in white to enhance light diffusion. sand the front transparent layer.
*_sep.stl printed in transparent.
*_cap.stl printed in black.

To fill with your favorite "neo pixel" and arduino flavor, I used SK6812 RGBW leds with a ESP32.
