This lucky duck gets a new foot, with help of 3D printer

ARLINGTON,  Tenn. -- A duck that was born with a backwards left foot last November and needed to have it amputated is back to waddling again, thanks to 3D printing technology.

On Sunday, Buttercup the duck was fitted with a custom-designed silicone foot.

The Feathered Angels Waterfowl Sanctuary in Tennessee has been taking care of Buttercup and chronicling his journey on Facebook. They worked with 3D-printing company NovaCopy to print a replica of Buttercup's sister's left foot. Using that copy, the sanctuary was able to mold a silicone foot for Buttercup that could fit perfectly.

On Sunday, the silicone foot was attached to a custom-fit sock on Buttercup using a nylon retaining screw, and Buttercup was as happy as a duck.
