A handheld game controlled by an Arduino pro mini and based on the old Simon game.

Detailed instructions to make it and how to play are available on Github.

The enclosure prints in two parts, I printed the bottom part completely without supports, which is not the prettiest on the inside, but it works. For the top part I recommend blocking support structures for the speaker mount and hole, but using supports for the roof and power switch mount.

I printed mine in white PLA on an Ender 5 Pro (0.4mm nozzle) with 0.2mm layer height, 15% grid infill, and 4 vertical shells.
