Need help with scaling consecutive parts

Hello Forum.  I have to make a 7 segmented part that is like a "Russian Nesting Doll". The pieces have to have the same top and bottom profile in order to fit "inside" one another. But this is more like a spy glass than an a real nesting doll. Here is a picture of the first 3 stages. Is there some way in SW to make repetitive examples of a part? the catch is that the outer wall thickness of the cylinders has to remain the same as well as the center pass through hole.

I guess I can change these drawing feature if this is not easily achieved?

Thank you,
