I can't get over how difficult this particular shape is.
I tried making it in several of my other subD and Nurbs apps also and MoI is WAY ahead!(Well I could not do it in any of them!)

What is it in this shape especially that creates problems I wonder?

Anyway, for use in my normal 3D rendering apps I at least got a fine result eventually---with thickness!
(What a time waster!)
