Rayven "Bubba" Kahae is a 3-year-old boy who was born with ABS, amniotic band syndrome, which means one of his hands isn't fully formed. Thanks to a group called E-Nabling, who specialize in making 3D printed prosthetic hands, Bubba now has his very own Iron Man-style hand. He couldn't be happier.

Bubba's grandma was interviewed by KHON2 News, and she shared the footage of her grandson getting his brand new superhero hand. It's always nice to come across a feel-good story like this. The kid looks so freakin' happy with his new hand. Thanks to Geekologie for the tip!
