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.
I can't give you any STL files, because it is a parametric model. Parametric models require the consumer to set the parameters, and then generate STL files based on the configured parameters.
SCAD models 'are' the standard for parametric models on Thingiverse.
You can't open SCAD models in slicing software like CURA. You can open SCAD models with SCAD supported CAD software, like OpenSCAD, or the Thingiverse Customizer.
The Thingiverse Customizer hasn't worked for a few months. Content creators have no control over this. However, it is not a problem, because you can just open SCAD files in OpenSCAD directly, and set the parameters there.
