Friendly cube from portal game. Use litophane covers to show the logo with the light from inside. I used WS2812B 50mm led rings and arduino control. But You can use basicly any led rings that has 50mm diameter.
i added a 3mf for easy printing from bambu handy app, i gochu, but i didnt add the potato sputniiiiik peg and the ring holder because if someone is smart enough to need those pieces to build this as an led, they are smart enough to download the stl themselves on a desktop with makerworld lol i also made it 25% scale so its like a smaller easy to print size. maybe ill upload larger one too, and maybe ill try to see if i can make the pieces fit together perfectly maybe gotta scale one part upor down so they pop in supr easy no glue needed.
