Mendel Prusa 3D printer

This I started modeling few months ago, and then for unknown reason I just forgot about it. Now when I saw that someone has requested a 3d printer, here it is. Unfinished though. As some of you already know, Prusa Mendel is one of the Reprap’s low cost open source 3d printers. One of the ideas is for it to self-replicate. I modeled it after Mr. Gary Hodgson’s visual instructions. There are still few things missing in my model such as the extruder, etc. Whoever digs a little bit deeper into its design, and this pdf instruction http://garyhodgson.com/reprap/prusa-mendel-visual-instructions/ , will notice what’s missing. OK, so go on...
