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.
When I was printing the main core my printer kept knocking over the model about three-quarters of the way up (I used the repaired file), so it never finished. I thought it was just my printer, but it printed the shells fine. I tried four times before I tried flipping it and printing it upside-down. It finally worked and is actually pretty good, but that's just my tip if anyone's printer is having trouble.
