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 have not had a chance to reprint it again but I am going to try two things. First is the "Outer Wall Inset" in Cura. The next one is to just scale up the model size a bit so that there are larger gaps between the bearings. If in Cura you don't see the Outer Wall Inset setting you might need to update to the latest build which I believe is 2.6.1 and then it is in advanced settings.
