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.
Tried both Simplify and Cura, having the same problem with both.
The neck is too thin, you need to make the wall thicker or the slicer will ignore the wall.
I managed to print it on Simplify by changing the thin wall behavior. But ideally the model need an update.
