A company named Soda Concept is selling 3D printed sunglasses for 39.95 Euros. What is so awesome about these is that the frames and arms are interchangable. If you get tired of one color, you can pop the lenses out and put them into a different color frames. Same goes with the arms. You can mix and match colors of the arms as well. The price is good, and the sunglasses look pretty cool. Read more about these at http://3dprint.com/7895/soda-concept-sunglasses/
