I wasn't even thinking about 3D printing. It will truly revolutionize a lot of hobbies such as modeling.

In my drafting class, I used SOLIDWORKS to draw a balancing toy which was then 3D printed.

The balance wasn't quite right, due to the printing process. As a means of reducing material use, the interior of a part is made less dense.

But, I've still got it. It doesn't have any real value, just like the test piece I cut on a lathe for a machine tool technology class.
