Thanks! Yeah, it's nothing in particular per-say, but this shape is based on a minimal mathematical surface called a "monkey saddle". This is actually a saddle ring (toroidal warp) consisting of 2 or 3 saddle stories, given thickness, and then other topological adjustments.
Thanks, I really appreciate you taking the time to look. Trying to understand the equations that make the objects is part of the enjoyment. One of the many reasons your gallery is so enthralling, with such a wonderful collection of knots and surfaces.
