(NEWSER) – Derby the dog is winning new converts to the concept of 3D printing. Derby is a husky mix who was born last year with deformed front paws, reports BuzzFeed. Lucky for him, an employee of a company called 3D Systems in Massachusetts took him in as a foster dog and eventually hit upon the idea of printing him new front legs. The result of Tara Anderson's idea has become a YouTube smash, notes the Dodo. Derby, incidentally, has been permanently adopted by a family.
