Cat Feeder Updated

This is an updated design of my original cat feeder. The base is designed to house a nema 23 stepper motor and the circuitry needed to control it. The hopper and spinner are also slightly shorter. The lid is identical to the original. For more info please see my blog post about the feeder (https://joshuarobotprojects.wordpress.com/2017/03/30/cat-feeder-v4-0/).
