Removed the hole in the center back part and added a socket to insert an USB-C plug like this one https://amzn.to/4aJoYvo as power supply for the LED strip, I used this: https://amzn.to/3vGrnbv.

Colored one layer white, especially to make the logo a tad sturdier. Otherwise it will break easily between the colors. On the back it also made sense, to have a better light yield.
