pyopenscad i believe is used to script up complex functions
to generate objects surfaces because openscad is relatively simple
language and doesn't have the giant features of python.
Openscad is evolving - the latest version does tapered screw spirals. I
made a tapered screw chuck type thing that is 1 inch and
so strong it can take a spanner to tighten it and thread don't break.
Unlike nylon screws. And this thing is done in PLA :( !

Anyway lots of designs released in openscad at thingiverse.
Search for parametric designs - reduce chance of re-inventing wheel.
