Use loft with matching vertices.

I mean more simple one, like this:

Make your profile and a helical path then sweep the profile along the path.

I tried it before, but this is what i get:

I was able to generate the sweep see link . But If I attempt to increase the revolutions of the helix more than what I have now, it will also fail. Sorry but I don't understand why and hoping that someone can explain.

@_Dave_ something to do with self-intersecting geometry probably

Here is my attempt which is robust, but takes a few steps to model https://cad.onshape.com/documents/b12c2467c2176fcf852669e3/w/b69da02b940d7ccb572be036/e/bc72fffa6400cdb7eed49a07

The trick is to model just a section of it.
