Printable cat feeder

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](https://www.amazon.com/gp/product/B00013K8O4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) cheap cereal dispenser and print these three parts.

Assembly:
* Use the screws that come with the servo to attach it to the mounting bracket (they are self tapping)
* Put the printed pin in instead of the knob that comes with the cereal dispenser (there is no need to to use screws to attach the arm to the servo)
* Attach the bracket to the collar with two M3 screws - about 20mm long or so.

Note: photo shows a slightly earlier design, the files uploaded fit better than that early revision... ;-)
