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.
The X ends and leadscrews are custom also. The leadscrews will be available in my shop in about 2 weeks. The X ends are included in the Zip file but will be listed as a separate item on Thingiverse as soon as I get a chance to add it.
Note that these new X ends are designed to reduce Z axis binding, so they require 4 extra bronze bushings on one of the X ends.
