"Nokia is releasing design files that will let owners use 3D printers to make their own cases for its Lumia phones. Files containing mechanical drawings, case measurements and recommended materials have already been released by the phone maker. Those using the files will be able to create a custom-designed case for the flagship Lumia 820 handset. The project makes Nokia one of the first big electronics firms to seriously back 3D printing."
