There is a modular origami version of this by an English man called David Brill - a 'double-star flexicube' - https://brilliantorigami.com/diagrams/It makes two of these which can nest inside each other - which I guess you could do with this also.
You can make 'char-cloth' in the same way. Char-cloth is like charcoal, but made out of cotton cloth - like a piece of old jeans fabric, or an old cotton t-shirt. It's great for lighting fires in survival-type situations. You can get a great big hot ember easily from a spark or a magnifying glass.
