This is yet another cat feeder design. It has the nice property that it is fully printable (aside from the container which comes from amazon) and uses an RC servo for dispensing. Basically works fine if paired with a Rasberry pi or somesuch to turn the servo on briefly.
You'll want to buy this cheap cereal dispenser and print these three parts.
Assembly:
Note: photo shows a slightly earlier design, the files uploaded fit better than that early revision... ;-)
