Some time ago, Apple uploaded the CAD diagrams for anyone interested in building cases for the iPhone, iPad or iPod. It took Core77 a lot of time and patience to overlay them on the product photos, but they were worth waiting for.
Apple made the drawings available for potential case manufacturers, but when you download a file from their site you'll soon understand why Core77 felt the need to superimpose the measurements over the official product shots. These would make great desktop wallpapers - if your monitor was just 500 pixels wide, that is. [Apple via Core77]
