Icosahedron - Onshape FeatureScript

My biology class inspired me to design this when we learned about viruses. I've learned a lot about Onshape's FeatureScript while working on this (which was part of the goal), as well as practiced a bunch of trigonometry (which is good since I'm taking a calculus class right now).

The link for the feature is:

It should allow copying the document to allow editing the parameters,
