Hollow Mini-Mendel

This is a Mini-Mendel ( http://www.thingiverse.com/thing:1745 ) where many parts have been shelled (hollowed out) to 1mm (some 1.5 or 2mm for better printability).
This shall allow to use even less material in printing and apply the material where it counts for the mechanical structure (2-3 shell layers but very sparse infill).
Where appropriate I added supported and teardrops to make the shelled parts printable.
The idea is to supply the enormous demand for Mendel-parts by producing batches
