This is newer version of my ESP32 DevKit V1 case, suitable for 3D printing. It has an exposed USB port and a snap-on lid with ventilation, LED cutout for viewing onboard LEDs, and two buttons built-in which less you depress the on-board ESP32 buttons without opening or removing the case.

It can be printed without supports (at least on my Prusa MK3S), as the big underside is hollow, and has some beveling to expose only a relatively small overhang area.

The main difference for this case is the pins are completely enclosed in the case, but are open so that you can still connect things to them.
