Pet Feeder

Update 2/24/2022
Redesigned the drive shaft to be a little heavier duty and paddle to fit.

Wanted an automatic feeder for the dog. The screw type feeders would jamb and the cereal dispenser type were too small. So I designed a cereal type that uses 2" PVC fittings.

This feeder is for a dog but will work with most pet foods. Besides the printed parts you'll need a 2" PVC Tee (and not the kind for DWV) The Tee has to be straight without a swoop. A stepper, power supply, stepper driver, Arduino Nano, RTC module, piezo buzzer, a momentary button and a buck converter. Also nuts and bolts to mount the stepper and a 608 bearing.

All pieces are PLA except the the feeder paddle. Make it out of TPU.

After printing the feeder paddle, cut the paddles at the disc base about half way down. This will free the ends to flex and not jamb on the food.

Insert the 608 bearing into the bearing support. This is glued to the round end of the 2"PVC coupling.
Mount the feeder paddle to the driv
