About this model

Very minor remix of the great original thing - shortened the vertical dimension by 4mm to fit on my Prusa I3 Mk3 frame. Either the aluminum plate adds a rounded corner or the power supply sits a little taller, but the original wouldn't fit. It has a whole bunch of slots for tools I don't have. Sliced wit Slic3r Prusa Edition, printed on a Prusa i3 Mk3.
