Concertina bangel

The idea of this ban gel is inspired by the concertina the way it moves and its flexibility, the old cameras were designer ed based on that idea, on the picture I used the old camera to investigate, and take close look on the concertina, above are the concept sketches of how the ban gel is going to look like, basically it is going to be half solid and then half concertina and I am still planning it on CAD rhino on how I am going combine all the pieces together.
