Vacuum Station Base

Inspired by something so simple, I couldn't believe it. I backed his project because I wanted one and if the project updates weren't convincing enough, I went and derived my very own for proof-of-concept.
The project is currently live as of June 18, 2013 and my inspiration can be found at:

This is really a proof-of-concept. If you like what you see, back his project to show support.
