Here is my play on a Mini Wolverine Chibi Light Box. Below are links to the USB plug i used, as well as the lights!

In order to print in more than 4 colors, after slicing, go through the first few layers in preview, and make sure to write down the print order for the colors. I left black and yellow in 1 and 2, then alternated 3 and 4 for the other 4 colors. All you do is watch for a color to finish, then swap to the next color while its printing another color. Super simple!

As for wiring the lights, i used a simple 2 wire USB connector, soldered the two wires to the board, then used hot glue to hold everything in place. Any issues, feel free to drop a message!
