I've been using AcuRite 06044M sensors with home assistant and wanted to wall mount them, but the options I could find seemed more complex than what I wanted. This model is small, prints quickly, and hides behind the sensor once installed for a clean look. This will probably print faster than it takes for your printer to preheat and needs no supports.
Uses a single small poster command strip.
The author marked this model as their own original creation.
