These are the 3D printed parts I designed to convert a Zervo Dry Food Dispenser into an automatic pet feeder.
The feeder is powered by a Raspberry Pi, Geared Motor, and Relay Board. It is programmed to dispense food three times a day and send a picture via email every time it dispenses the food.
More info on this project can be found at HERE on my website.
The food Chute is printed in 3 pieces for ease of printing and then glued together. The
Pet_Feeder_Chute_Ring is glued to the Pet_Feeder_Chute_Top only at the center/rear of the Ring so the sides can be squeezed together to be inserted into the bottom of the dispenser hopper.
The mount for the internal electronics is also printed in 2 pieces for ease of printing and it is also glued together.
I have not tested the coupler for the motor but it should work.
