Recreating physical model in grasshopper help

Hi everyone, I’m working on a project which involves a series of connected tubes as you can see from the attached photos, I want to develop it by creating different iterations in grasshopper but I don’t know how to get started.

Does anyone know how I can recreate the form in Grasshopper which would include parameters which can change the length, thickness and angle or rotation of some of the tubes?

I was thinking of using the pipe command on a poly-line but I’m unsure if that will work.

The form doesn’t have to look 100% like the physical model just similar to the concept. I’d appreciate any help!
