Twisted star box

This is V2 of my twisted star box.
The model is now almost fully parametrized, making it possible to change parameters like base radius, height, base/lid ratio, number of edges in the star and regenerate the geometry from within Art of Illusion.

To regenerate/edit the model, our under development and undocumented MetaCADEvaluator plugin is needed. This is part of the development version of CSGEvaluator for Art of Illusion:

Notice how the AoI file is only 12kb while the stl version totals ca. 5mb.
