Couldn’t resist, since it’s so similar to this. But my experience with meshes and collisions is meager. At first, nothing seemed to work, so I focused on just a single strip:
Like the above thread, the twisting “breaks” when it overcomes the mesh strength (my assumption). But I also tried giving the strip mesh twice as many cells along its width:
It rapidly creases as it twists, which is what I’d expect. So it greatly depends on what you’re interested in simulating – thin spring steel vs. paper vs. fabric…

I then tried adding a second strip. I found the SoftBodyCollide component (“collisions between a collection of deformable meshes”) but no luck getting it to work. Same with the Collider. Then went to @DanielPiker 's example repo and found cloth collide, which uses the SphereCollide component. Not sure why, but it works:
Not sure any of this will be helpful for what you’re trying to do, but I learned a bunch!
