I designed the case for a Raspberry Pi Zero in Fusion 360. Design inspiration was from a previous Adafruit designed Raspberry Pi Face case for the B+ model. Noe Ruiz helped with showing me some design changes that could be made to improve on my original sketch. I also used the snap fit design shown on a Layer by Layer video to make the case so it requires no hardware to assemble.
