What are you Favorite 3D printed models that you have seen or even printed yourself. I love learning about 3D printing and the types of things that you can create. In the GrabCAD Office we have a functional Electric guitar and most of the parts were 3D printed. Took a bit of trial and error but we were able to get it done.
Here are some models that we have arounds the office that were 3D printed on our Stratasys Machines.
