The casing is made from scratch. I started with making four 9x9cm planks. Then I printed some patterns out and taped them to the edges to make some finger joints. I mounted my jigsaw upside down and added a plank so that every cut is equally deep. The next step was to remove all the black parts.

Everything fitted very well from the first time. I didn't expect that. The front is some plastic with an extra layer butter paper. I didn't found anything better at that moment.

The electronics are mounted on the backside.

On power-up the ESP shows some animations until it's ready for use. I added some separation planes inside to set apart the individual pixels, and make the animation beter visible.
