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.
Read the instructions above please. ;-) Source files were posted the day the design was released. In addition to the native Alibre files, I have two different STP file versions that are compatible with the majority of CAD programs.
Like every other Thing on Thingiverse, the license is listed at the bottom of the column to the left.
