About this 3D model
This is (what I think to be) a complete set of all the printed parts you'll need to assemble your own Mendel90 Reprap variant. The parts are all laid out to fit on a MakerBot Replicator build plate and have been cleaned up by cloud.netfabb.com, so they should be good to run through your favorite slicer and print.
