This was a fun, inexpensive, and pretty easy project. The whole project from starting to print the parts to an operational machine was about two weeks. Most of the parts were printed on a very cheap Anet A8 3D printer (I printed the red parts on a cheap and tiny Monoprice Mini). The other hardware parts were bought at Ace and Lowes. The electronics were pretty basic and were purchased on eBay. All of the files are available for free at http://www.thingiverse.com/thing:724999
Many thanks to Allted for this! Stay tuned in future weeks for lots of projects.
