Got surplus epson SX100 . It was missing a part which supports paper pages fed into it , so they do not bend over and fall on the back . Creating replacement was fairly quick, though challenging part was to make it fit my build platform. I've used puzzle cut library http://www.thingiverse.com/thing:35834/ which made the process totally painless :) Files avail are original blender file, puzzle cut library and scad to allow cutting stl model, and stl models ready for printing . Enjoy!
