3D printers have been used to create a lot of cool things – from clothes and musical instruments to parts of an F1 car and even a working gun.

These duck flippers are possibly the best 3D printer creation yet though, as they've helped an injured feathered friend walk again.

When Phillip the duck lost both of his feet to frostbite, he was almost put to sleep.

But mallard maverick Vicki Rabe-Harrison came to his aid, and has got Phillip back on his new feet.

With the help of local technology teacher Jason Jischke, Phillip was made a brand new pair of flippers using a school's 3D printer.

Perfected over six weeks of trial and error, the 3D printed feet have let him walk again, and allowed the animal to be submitted to a local Wisconsin sanctuary.

"He picked it up real fast and I'm sure he'll learn to balance again, and be able to waddle around with all the other ducks," Ms Rabe-Harrison said of the makeshift leg extensions.
