Inspired by other designes but this one lets you slide in your LED-Strip into the print → no adhesive required → LED-Strip won't fall off over time.
WS2812b led strip, make sure you choose IP30 any other IP rating wouldn't make any sense and will not even fit.I would recommend buying a strip with 60 leds/m.
