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.
There is another piece, smaller, that I would suggest to be printed prior to this one - http://reprap.org/wiki/Sfacthttp://reprap.org/wiki/Sfact, _40x10.stl
I'm using both to calibrate my printer and both are awesome, IMO.
Thanks for sharing!
