This is my digitally fabricated auger based pet food dispenser. You simply load the pitcher with pet food and it is automatically pushed with the auger screw into the dish to feed your pet. This has been tested to work with cat food and designed with a cat in mind. Actually this is going to be a Christmas present for my sisters cat.
In the past year I have been working to up my game when it comes to fabricating parts for my projects. If you were to check out some of my older Instructables you would see most things I made were built with three basic tools, a drill, a saw of some sort and a dremel. These tools serve me well but I had to limit my material choices and construction techniques to match the tools. I was always designing parts around these limits and trying to source pre-made parts whenever possible. I had some success with this but always thought it would be nice if I could make cuts a little straighter and make things with more complex geometry.
So during the end of 2011, I started working on a cnc router. I finished it in Febuary 2012 and posted all the plans for it here on Instructables DIY CNC Router
It has been an awesome tool and I have used it many times. I've made things for my aunt, my sister, my cousin's eagle scout project and a fishing poll rack for my Dad. Around the same time I was finishing up the router, MakerBot released the Replicator and I got caught up in all the hype of 3d printing. I poured myself into this new subculture I found on the internet and I when I emerged from my fasination with these cnc hot glue guns I decided to buy my own 3d printer. There are many DIY level 3d printers available but the one I decided to get was an M2 from MakerGear
. It is my opinion that this printer has the highest quality components and uses the best manufacturing techniques of any DIY level 3d printer currently available.
So now that I have a CNC router and a 3d printer I decided to work on a project specifically geared toward using these tools to take advantage of their capabilities. The pet feeder is that project and in this instructable I will to explain how I used the machines to create some unique parts.
This design for an auger screw based kibble dispenser was inspired by Tunell
but I created all of my own 3d models for this design. I have uploaded the design files to Thingiverse as well Pet Feeder Thingiverse #34100
