Parametric shrouded propeller

This is a parametric shrouded propeller. Easy to change lots of things about it like thicknesses, number of fins, angle of fins, etc. Made in OpenSCAD. I would like to eventually change the fins to be more like airfoils or something, but the current design prints quite well without supports or raft right on a heated build platform.

I'm going to be using it on a DIY R/C boat. Of course, I just found the OpenROV propeller...

I'm also working on an improved propeller with elliptical fins that
