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.
If by "other sizes" you mean number of slots, it's already customizable (use the Customizer tool to select the number of slots)
If you mean for other machines, I'd be happy to, but only have the 1924 Gearhart for comparison at the moment.
If you mean something else, please elaborate.
