I made this case for an inductive energy monitor.
The case is divided into three parts and also has plastic part that makes the ESP32 and PCB stay in place.
The case snaps shut without any fasteners. Screw holes are provided as a an added security measure.
Im adding the gcode, stl and fusion360 file so you can adapt as needed.
Im also adding the circuit diagram and pcb diagram in case you are interested.
Code for the project can be found here:
