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.
As noted in the instructions not all machines print as finely / precisely as others. This is why a 'loose' version file is provided... plenty of people have printed these with success and great feedback but ensuring your machine is well set up is important. Printing in the middle of the build plate, level build plate, effective filament fan all count... but, as per the comments and images, they work fine for lots of people so hopefully you can achieve the same.
All the best
