This was actually one of the first projects I did with my first 3d printer a couple years ago. Back then, I did not really know how to use a 3d printer (+ I had a quite shitty one from Conrad, the RF100 XL V2), and I did the 3d modelling in TinkerCAD. Therefore, the printed model was not really ideal. Also, the power supply was some weird thingy I got from a friend, so that was also not that great.
After I got more and more into 3d printing and 3d modelling, I decided to create an improved version. It is a new case, alongside with a proper ON/OFF switch and a ESP32 for monitoring via ESPHome.
As for the wiring, I followed the guide from syssi on their GitHub profile: https://github.com/syssi/esphome-dps, so there is nothing really I could add to that. There was a issue with it first not detecting the DPS, but I think that was just a broken solder joint, because after swapping RX and TX two times it worked again.
Where to get all the files / how to build it myself?
