Josh Ajima is obsessed with giving students an entree intro 3D printing technology. A blogger, designer and educator, Ajima recently created what he calls "The Hackerspace Heroes of 3D Printing: Designers and Artists Series #1." It's a gallery of 3D printed art and design objects which are placed inside a classic gumball machine vending device meant to give people an introduction into 3D printing and the artists who are pioneering the technology.

I thought this was a pretty cool idea. I would probably throw a few bucks into a machine for a random 3D print, and those who have never seen a 3D printed item before would probably be even more likely to do so.
