I'm new at this, but here's what I was thinking.

Make a cylinder. Extend it LONG, or create a curve.

Make sure there's a LOT of subdivisions. Change it to vertex mode. Select every OTHER "ring" of vertexs. It may actually be easier to change your perspective mode to side view in order to select them.

Use the scale tool to shrink it.

Select the OTHER vertexs that you did NOT shrink (just Select the entire thing, it will deselect the ones that are selected). Then use the move tool, and bring them closer to the shrunk vertex.

I know it may seem like a hassle, I just don't know any other way. Maybe the more expert Maya users can help.

If you want to look like the dryer tube, another way you can kind of make the texture look a bit weird, is while the "shrunk" vertex is selected, use the rotate tool to give it a slight twist.

That way when you apply a texture, it gives a slight twist look.

Lmk if it worked!
