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 concept is interesting but when printed the size of the moving parts is exactly the size of the wholes (so they don't fit). I tried importing the .stl into OpenSCAD to make the wholes bigger but unfortunately I hit an error in openSCAD (some exception when rendering).
I might need to create my own openscad files from scratch for the upper and lower plates.
