This was a quick video for the 3d printed pulley I made for a car antenna. Published on Thingiverse

Originally only a video I sent to my mum and dad, but needed a video for the 3d printed pulley, so here it is.
By the way, I control the door via an ESP32, using ESPHome on Home Assistant.
I can also monitor the level of feed in the hopper using a cheap ultrasonic device, and the battery/solar voltage on the coop. Might make a video on that one day.
