G4 RF1 Gasmeter & ESP32-CAM Mount

This project contains a mount for the G4-RF1 gas meter from Herman Pipersberg Jr. GmbH to attach an ESP32-Cam to it.

The ESP32-Cam can be used in combination with the project “AI on the Edge Device” (GitHub: https://github.com/jomjol/AI-on-the-edge-device) to read the gas meter and send the measured values to Homeassistant via MQTT.

While working on this project, I managed to reduce the filament consumption from approximately 100 g of PETG at the beginning to about 51 g now, which leads to a reduction in consumption of almost 50 %, while the stability is still far more than sufficient.

The 3D model consists of two central elements:

Gas Meter Mount

The attachment, which is placed directly on the gas meter, is designed to fit tightly and simply needs to be slid onto the front. This part also has a recess to accommodate an LED strip (WS2812 LEDs) for better lighting.

ESP32-Cam Mount

The second part is the mount for the ESP32 cam. As there are different camera models with different sensor orientations, the bracket was designed so that the microcontroller can be placed horizontally or vertically to utilize the maximum image width. In addition, there are cut-outs for the internal LED of the controller for both orientations and a cover for one of these two, which is not used accordingly.

If you have any suggestions for improvements, need adjustments or help, feel free to leave a comment and I will try to respond as soon as I can.
