A bumper case for the ESP32 Rainbow, a reimagined ZX Spectrum on a single board with capacitive touch keys. You can get one via Crowd Supply.

Designed for the board to slide in, and optionally secured using 4x M2 8mm screws at the corners. There is a pocket at the top left for a LiPo battery if desired. I tried to leave as much of the information on the back silkscreen visible as possible, with the exception of the area where the battery pocket sits as I didn't see a good way around that.

I printed using Bambu Studio and split it in half 50/50 with hex plug joints. It does just fit on a 256mmx256mm print bed, but this worked nicely as a two part assembly option.

Designed in Tinkercad, model is here.
