It seems like every time I see a 'cool prosthetic' it's something the person has created at home, or with the help of a university professor.

I just find it really interesting that, of all things, it's prosthetics that are home made more than anything else I see. 3D printing, along with the need from something completely custom, seems to be creating a culture of DIY for replacing your own limbs.

It's very strange if you think about it.
