A modello was the finished preview a Renaissance artist showed the patron, so they could see the work before it existed, and the workshop built from it. That's the job here: let your buyers, investors and fitters see your product before it's in front of them.

An example
A hand winch of my own design: the video, and the same model as a 3D view you can turn, open up and step through.
