How strong is sheet steel? I am thinking of a rugged Kindle Case?
I have thought about sheet steel, flattened PVC and wood.
Wood adds a decent amount of thickness to be rigid enough, and I wouldn't know where to buy thin hardwood planks.
PVC I don't believe is all that rigid once it's been turned into flat sheets.
Sheet steel is readily and cheaply available on Ebay between 0.18mm (0.007 inches, or 36 gauge) and 1.7mm (0.06 inches, or 15 gauge), and probably higher. I don't care about the weight as much as the thinness and strength/rigidity, so I thought sheet steel might be the best option but I've never worked with it. Suggestions?
Edit: I would add some sort of shock protection, ie: neoprene, but it's not dropping that I'm worried about.
The design would be two flat pieces sonnected by a fabric "hinge," similar to this:
I would add raised edges surrounding the Kindle on the "bottom" piece of metal, so that the two pieces wouldn't squeeze the kindle between them when pressure was added.
