This is a remix of jomjols awesome water meter project.
I remixed it in order to

• have less parts to print
• avoid the requirement of supports
• make use of a ESP32-CAM-MB module which has USB on board for power and programming

Downside is that you now need some screws to put it together. You will need:

• 3 x M3x10mm DIN912 to connect tubus and adapter
• 2 x M2.5x6mm DIN912 to connect ESP32 housing and tubus

I added fusion360 files in for easy modification. Most likely you will need it for the adapter as every meter seems to be slightly differen.

The ESP32-CAM 3d file I used for the construction was found on Grabcad. Thanks to Jan Jazek for providing it! Link: https://grabcad.com/library/esp32-cam-1
