About this 3D model

I tried to make the single plate version (http://reprap.org/wiki/Prusa_i3_Build_Manual#Single_Sheet_Frame_Style) more rigid. The aluminium parts are waterjet cut from a 6mm sheet of aluminium. (500mm x 800mm) I made an enclosure from some triplex and acrylic(not in pictures yet). The motors (except the extrudermotor) are outside the chamber to prevent them from getting too hot.
