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 work at Solidworks and can only provide source files for this program. If you understand them, here they are. It seems they are available for import into Fusion 360. I have not tested the version without magnets and use it myself with magnets. This is the most convenient option. Unless it is necessary to make grooves for specific magnets.
