hyperbolic solid

This is a parameterized hyperbolic curve rotated around its transverse axis to make a solid.

Both horizontal and vertical versions are in the OpenSCAD script! Adjust to make the hyperbolic solid of your dreams!

Horizontal gives the results we needed with rotate_extrude, but the vertical axis shape is fun and possibly useful too.

This solid was designed to be part of a multi-reflector cassegrain style antenna design for 122GHz amateur radio inspired by Paul Wade W1GHZ's writeup. Link below!
