3D printers can also make helpful things

I can't help but think that the timing of this video could not have been better. While the conversation is turning towards the potential dangers of 3D printing, it's good to remember that 3D printing can also do very, very useful things, a point I've made on numerous comments around the web. Please take a moment and watch this video, as well as the Magic Arms one if you haven't seen it already, to see the force for good a 3D printer can be.

3D printers aren't going to be the end of the world. They're a tool and they can make great things. Of course all I use mine for are chess sets and jewelry, but that's not the point.
