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 you are using a printer that has a moving build plate in one axis, I'd rotate the print 90 degrees to prevent the wobble. Another option is printing it with a much larger brim or raft. If that doesn't work supports will help keep it upright. Hope that works!
