Want to take 3D printing into your own hands? The LIX pen looks like any writing instrument, but instead of drawing with ink, you can do it with malleable plastic.
Create scale models, 3D script, accessories, and whatever else you can think of. This concept first hit Kickstarter as the successful 3Doodler, which is much larger in size. The LIX 3D Printing Pen is easier to use and costs less too.
