Hendecagonal Hyperboloid

Description

This hyperboloid is constructed from affine hendacagons (11 sided polygons). The three polygons at the center are all congruent and mutually orthogonal although the geometric construction technique does not require them to be so. See other similar models in my [Hyperbolic Tilings Collection](https://sketchfab.com/davidhall/collections/hyperbolic-tilings)
