I made this a long time ago, partially to put my (then brand new) MMU2 through its paces, and partially to impress a lady. It went pretty well on both fronts.

This is not a simple model to print! It took over 24h to print back then, when I used my MMU2, thanks to the roughly 4000 color changes at 0.1mm layers. I haven't taken the time to print it again on the XL5T but it should be significantly faster.

The electronics used are:

• Arduino micro
• Micro USB port
• LiPo battery
• TP4056 LiPo Charger
• 1x WS2812 LED
• a little power switch
