MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I admired, made and used first the one at: http://www.thingiverse.com/thing:247992
but this one, based on the same principle of deflecting the forces from the Z-axes, is even more simple and beautiful. ;-)
Thanks a lot!
