ESP32 Case with Holder for Planters

I've designed this case for my Planters, so I could have a wireless device measuring soil moisture and control the small water pumps to water the plants automatically, specially on vacations.

The project takes 4 M3 screws and the holder is glued on the crossbar.

ESP32 will be a tight fit but it has space for Dupont connectors inside and has an opening for the USB port for power and another for the sensor and control wires.
