This mount is designed to attach an ESP32-CAM microcontroller to an gas meter. Together with the open source firmware "AI-on-the-edge" (https://github.com/jomjol/AI-on-the-edge-device) of the user Jomjol it can read the gas meter automatically and send the current counter status to a server via MQTT.
The recess allows an upright mounting of the ESP32-CAM module. I mistakenly assumed that with this mounting direction, the images would be generated in landscape format. Unfortunately, this is not the case, but the housing and the distance are still sufficient to use it for the above purpose. AI-on-the-edge allows software rotation of the image.
It is a good idea to print the model with black filament to avoid unnecessary light reflections on the meter glass. I realized this too late, so I printed the mount in white, which also works with a little fiddling.
In order to create controlled conditions during photography, it would of course have been even better to design a closed housing. However, this was countered by the longer printing time and higher printing costs. Since my meters are located in a permanently dimmed utility room, I opted for this solution. The advantage is that you can still read or check the meter values manually without removing or converting them.
Remixes and improvements of my model are welcome though, you can find the FreeCAD model in the download section as well.
