Rounded Accordion Shape

Hello,
I'm a student currently working on a project where I need to design a jet boil camp stove I'm working on the heating element and I'm lost on what to do to make this accordion folded piece of aluminum
If anyone has any advice on how they would make this in onshape please please let me know, I honestly don't even know where to start.

Here's one way. There is a tiny flaw where its not quite tangent at the joints on the bottom… but it should give you one idea to run with.

Here it is smoothed out with a little help from some maths.

This is a great use of the Wrap tool! To further riff on the two good models above here's a way that's a lot faster to regenerate and more stable to changes to the number of bends.

All of that said, @Joanna_Maratos depending on what you're doing, you may not need this detail modeled at all, and you may opt to just represent the space it takes up with a very simple revolved square.
Thank you Oliver for doing the math… It was way too late for my brain to do it. I probably would have done it today had you not.
Evan, also thank you for pointing out how late it was. LOL I meant to do part pattern. I revised my version for that. Way better than the boolean path. my regen time is twice yours for a 90 instance. I'm wondering what pc specs you are working with? as I am in the market for a new PC.
Joanna, I second Evan's comments about simplified version. A simple two circle extrude can also serve well if simplified geometry is acceptable.
@MDesign, the regen times in Onshape have nothing to do with your machine… All the hard math is happening on the servers. However the regen time can vary somewhat depending on the server load…
ah that makes sense. Probably doing it on a Monday is slower than on Saturday or Sunday. Interesting.
