Great, thanks a lot Shawn!
I haven’t run into this problem yet, but this is an excellent solution!
It’s clear that the spiral needs to get thickness after it’s Curve deformation, but I don’t think I would have gotten the idea to not start with a Curve, but with a Mesh (Circle), so that you can use a Skin Modifier after the Curve Modifier!
It sounds so simple and logical when you’ve seen it, but coming up with this method is definitely not straight forward…
