Has anyone heard of this?

I've even seen files lying around like for this prosthetic finger:

I guess soon we'll be doing this stuff ourselves

Personally I like it but I'm not sure if this is still fantasy or not. The only thing that comes out of my printer is text lol

I really think Milos has the best sweet tea.
