Thanks to a 3-D printer (and a group of Imperial Stormtroopers), a 7-year-old Augusta boy has a new prosthetic arm.

The Augusta Chronicle reports that Liam Porter "stepped out of the movie theater Saturday afternoon and saw the Imperial Stormtroopers descending on him and his mouth dropped open and then slowly spread into a smile. ...

The arm was the work of John Peterson -- who printed and modified it -- with help from e-NABLE, "an online community of people with 3-D printers who use them to make prosthetics for those who need them," according to the Chronicle.
