Here's a feel-good story that's worth high-fiving over.

Five-year-old Texas boy Keith Harris was born with symbrachydactyly, a rare congenital condition that resulted in the fingers on one of his hands never separating.

Thanks to amazing 3D printer technology - and the E-Nable Organization - Keith now has a special Iron Man hand, which he recently showed off to his classmates with a round of handshakes, fist bumps and high-fives.

"I was excited a lot," the adorable little boy said to a reporter.

Keith's 3D-printed hand only cost about $50, as opposed to the $40,000 is could cost to get a prosthetic hand.
