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.
Successfully printed them using Slic3r (posted in makes section) . However, I may know what the problem is and I'll try to fix it ASAP - those 3 models have wrong-facing normals. Inverting normals should do the trick for now, and I recommend printing 1 at a time.
P.S. Slic3r autofixed these for me btw
