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.
There is no magic here. I remixed from hofftari's original design by importing his STL into Fusion 360 and then adding my own new features. I'll PM you guys with links to my Fusion 360 model or an exported STEP file if prefered, but it won't be much different from you importing my STL's. Agree though that the fact that Thingiverse only really shares STL's is sort of silly when they ALL were generated from editable 3D models to begin with.
