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 actually have a v6 and tested it extensively.

That said, you are free to remix to your hearts content! I have provided a step file further down in the comments.
