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.
Please read the description. The Hot-end fan Housing is not always level from factory. you will need to slightly loosen
the 2 screws and and adjust it up. I have even installed the "Short" version on machines where the housing was so off that its stock scoop
was catching prints above layer 2. Straight from factory.
Look at the Make Photos from everyone on here and you will see the fan sits properly
above the nozzle in them.
