The 3Doddler, a 3D printing pen

Everyone knows how to use a pen, so we designed a 3D printing pen! If you can scribble, trace or wave a finger in the air you can use a 3Doodler. As you draw, plastic comes out of the pen, is cooled by an integrated fan, and solidifies right in front of you. You can draw on any surface and lift it up into the air to create your own 3D objects.
