I needed a bracket that would hold an ESP32 to my gas meter so I designed this. I made it snap on without any kind of permeant adhesion to the gas meter, since in the United States we don't typically own our gas meters. Seems to hold it in just the right place on my meter, your mileage may vary.
This was designed around ABG3D's https://www.printables.com/model/397880-esp32-case but should work for any ESP32 case with an external width of 32.5mm.
Built for use with troniko's https://github.com/tronikos/esphome-magnetometer-water-gas-meter project. Mount the 3-axis magnetometer to the back of the ESP32, then stuff it all inside the case. On my meter, the z-axis was producing about 10-15 uT difference between the ends of travel of the gas meter diaphragm. My meter is a Honeywell AC-250.
Printed in ASA to cope with the temperatures and UV that come with an outdoor print. Mouse ears required on the ends of the bracket, but it otherwise has good adhesion through and shouldn't warp if you have already had success with ASA printing. Model already accounts for slight shrinkage, but using a quality name-brand ASA filament will help. I used Flashforge ASA.
Sorry the picture is at night, but in true fashion I had to get this project up and running before the coldest days of the year so I could start to gather data on my gas usage! :)
