Case for WEMOS D1 MINI ESP32 with 3cm headspace

I needed a case with some clearance underneath my WEMOS D1 MINI ESP32 for a nRF24L01+ wireless transceiver to run AhoyDTU for a Hoymiles HM-400 microinverter for my balcony power plant. I couldn't find one that I liked so I made it myself.

I designed it for DIN7991 M2x8 screws and you need 4 of them. The screw holes have the necessary internal threads designed into them: when I print it as is using my Elegoo Mars 1 with factory settings I can just screw them in.
