Servo Fish Feeder for Flake Food

Inspired by this model https://www.printables.com/model/880006-automatic-fish-feeder-for-flake-food , I designed a fish feeder. I'm not good at programming wifi and other electronics, so I used what I understand. It is enough for my purposes, if anyone is interested, edit the STEP file according to your own idea.
