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.
That's completely understandable, don't worry. That's also the beauty of doing free models, we (the community) can help you! I could modify the CAD file to accommodate it in larger printers if you want me to, but as I have read in other comment of yours, it seems you don't want to share it for now. That's fine, just remember the idea of open source is that you don't have to spend your resources alone, when more people can help you.
I'll be printing with the old files for now, thanks!
