Ultimaker 2 Feet

In a shared environment such as [Cambridge Makespace](http://makespace.org/) the 3D printer can get moved around a bit by users, sometimes leaving them dangerously close to the edge or too close to the wall behind them so that the filament spool gets caught.

These simple feet attach to the desk and sit inside the base of the Ultimaker to hold it in place. They are completely invisible in use.
