Spherical Ribbon Pattern

Hey everyone! I’m been trying to figure out how to do this using grasshopper for a 3D spherical object but unable to make it work. Does anyone know how to do this?

Post your files that you have been trying to make work.

This one (below) is better, as it produces a continuous ribbon surface, lofted from two edges.

Here’s another example that has a twist & thickness. The edges are sharp and should probably be filleted, but I don’t know how to do that. Maybe convert to mesh & do some sort of mesh smoothing?!

The original image shows what looks like 3 concentric spheres, sort of like a Chinese patience ball. For the real world I guess you could suspend the internal ones with a short piece of clear fishing line. If I had a resin 3D printer I’d print one of these - oh well.
