Cute Smushy Parametric Tetrahedron

Parametric tetrahedron with Sierpinskis and extra smush

I had to add a couple of smush factors to get this to print, since the regular tetrix connects the base tetrahedrons with a single mathematical point. 

The overhangs are brutal, but with the print profile I've provided it should at least avoid dripping filament into empty air, like it did the first ten times I tried this. 

The scad file has some other factors you can change, to add hulls, concavities, and even a twist.

This is my first design and first print profile, very open to suggestions and tips.
