Despite having thousands of variants of ESP32 available on the market, I haven't found any case for the pico kit anywhere, so I made my own.

It has integrated buttons in top part of the case, accessible pin headers at the bottom and hole for USB connector. 

You will also need 4x M3 nut and 4x M3x8 (or longer) screws to build it together. 

The pico board sits quite loosely inside, I might make a version with less tolerance in the futur - OR just put a piece of paper under the esp32 board?

The holes for M3 nuts are tested on new prusa mk3s, so it might be possible they will be bit too small on printers that aren't tuned so nicely - maybe cleaning the hole with small knife or file would make it fit? 

On my settings it prints just over 1h:

Layer 0.3mm

3 Perimeters, 4top/3bottom full layers

10% infill

80mm/s printing speed

No supports needed.
