I was fed up with seeing my ESP32s wandering around my desk, so I created this custom storage box to keep them neatly organized. My ESP32s have 30 pins and are approximately 53x29x18mm. I don't know if all ESP32s have the same dimensions, but I hope this storage solution works for you. If you want to modify this model to fit your ESP32s, I have included a SolidWorks file and an STL, have fun ! Happy 3D printing !
