I've decided to build my own in my spare time, for integration with a CI/CD system (and for a friend who needs an "on-air indicator") ;)

"Industrial" Led Stack Light

I've decided to print the lenses in transparent PET-G and the base elements in black PET-G to take full advantage of the RGB. White PET-G would've probably been better for brightness, but I had none on hand and black looks better.
2023-11-06 - FIrst version failed, concentric walls with concentric infill does not play well :<
I've decided to use adressable RGB LEDs and some microntroller depending on what I can find in my drawers. It should preferably have Wi-Fi and be able to power 3 stacklights without an additional external power supply (besides the one on the board).
TBD, probably custom based on WLED by Aircookie
