This design is still under development. The idea is to be able to buy a 5in PCV pipe from your local hardware store, print some parts, and assembly a dry dog food dispenser.

This idea could also be tweaked for a cat feeder or Some how mount a stepper motor for an automatic animal feeder!

Buy 5in 40 PCV pipe Buy 2 608 ball bearings Buy 8mm thread rod (possibly 8mm bolt?) Print collar Print 2 5in feeders (half moons) Print 2 Dog bone knob Glue collar to 5in pipe Install ball bearings Glue 5in feeder to each other (align holes) Install 5in feeder assembly Drive thread rod though 5in feeder assembly Add knob mount on wall (Clamp stil need to be designed) Add dog food & enjoy
