Parts for automatic chicken coop door opener/closer
thingiverse
These are parts I engineered for integration into my daylight activated, Arduino driven automatic chicken coop door opener/closer system. I will update this description later with a link to a video tutorial and step-by-step instructions on how to build your own! I fabricated this using PLA, however, I plan to use Raptor PLA or ABS in a re-print if any issues arise. You will need to print one gear and two to three gear rack sections. The limit switch box is designed for sub-miniature limit switches, but it's not required if you opt for larger limit switches.
