While researching Cones and developable surface, came across an Oloid.
The Oloid shape is used in mixers, and as a toy which I never got to play with.
Have to get a 3d printer some day.

There are additional remarks in the script .js, regarding loft, mirror, and boolean union.

May try a torse "unwrap".


Here is a script to create an Oloid, based upon portions adapted from Lineweb script, and ToroidHelix script.

Using a higher line number will improve the Oloid "accuracy."
500 lines almost looks like a surface. Loft makes them a surface.
