Printerstand for Printrbot Simple Metal

My Simple Metal kept wandering around the whole desk while printing due to the vibrations. First I glued him to the desk with some adhesive tape, but that always seemed very crappy, so I designed this very simple stand.
I put four small (8mm dia) adhesive rubber feet t the bottom of each half, and two of them into the designated holes on the upper side.

The printer stopped moving now, and it looks very professional in my opinion!
