TP-Link Tapo C100 / C110 Base & Wallmount

As I wanted the base in a different color than white, I made this from the original model. This model use the same distance for the screw holes as the TP-Link original mount. I made 2 versions with different tolerances, as the original model was not tight enough to hold the camera in place.

I use this as a camera for PrusaConnect, following this guide: https://gist.github.com/nunofgs/84861ee453254823be6b069ebbce9ad2

It requires a Linux based computer of some sort to capture and upload images using ffmpeg and curl. I used my Raspberry Pi running Home-Assistant Core. I did not use Docker, but set up the bash script to run as a service instead.

Adjust the paths, filenames, camera IP, camera credentials, token and fingerprint to your needs.
