RGB 16 Segment LED

My ascii 'little a' is 98, according to my array. Not sure why. But here we have: text! Finally - before I was running the demo script from adafruit.io, that surely looked nice.

as requested by @Stefan-Xp

I wanted to power my arduino and the wsb2812bs from the same source when running, but didn't want to kill my usb port when programming, so I used some diodes from a rectifier.

Black plastic was by choice, I was afraid of color bleeding, if I print in white. I added a coat of primer spray and will later spray it white for highest reflectance. Not sure about the toplayer yet. Might print something with z-glass from zortrax finally.
