Dad Prints His Son a Prosthetic Hand on a 3-D printer – and it’s Awesome!

What do you do when your child is born without fingers on one hand? If you’re Paul McCarthy, you print him a new hand. Literally.

The cost? About 5-bucks vs. 20-30 grand. Wow – file this under amazing.

This kid is a pretty cool. And guess what? His Dad is pretty flippin’ cool, too.
