Snap-fit case for ESP32 D1 Mini, USB-C version. 

The micro controller fits very snug in the clip fitting, it won't move so no screws or anything needed. Some air vents each side, and the case has some headroom so you could mount other sensors onto the inside of the lid. 

Print fine with no supports needed, and I've used PLA+, PETG, and ABS with good results.

I'm always tinkering and improving, but I've used this case quite a few times now and it's always turned out well, so figured I'd share.

Be gentle with any criticism please - first model I've shared and I'm 100% not a designer :D
