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!

printerstand_1 is for the side near to the printing bed, 2 is for the other side (actually there is not much difference, two times number 2 would work as well. two times number 1 won't!!).
