Hi Lordfox, here's one attempt attached.




I used a method of initially building a straight tube, doing twist on it and then using Flow to build one section. But in doing this I found that a uniform twist is not the right kind of shape, it's sort of offset to one side. So I used the ease-in/ease-out option in Twist to kind of shove the twisting to one side. That build a kind of base form, I extracted some isoparms from that and then did a loft through those, and used Blend to connect the pieces together.

I'm still not really sure that it's feasible to really construct something exactly like your image out of one continuous piece though, it's kind of easy in a 2D sketch to apply painted on shading in ways that are not very easy to actually construct in 3D.
