Pet Feeder (Auger based)

The start of an automatic pet feeder project I'm working on.. The motor mount in this design is for a NEMA17 stepper, but that should be easy to change. The exit elbow is not finished, needs a little work. The finished project will be run from a Raspberry Pi with camera to see if cats are feeding... Update: 2016-01-13 - New exit elbow All parts are printed and assembled, now time to do the electronics and stepper driver.
