Ordinary.

This is part of the guts of a food mixer.
A mundane item.
What could be simpler?

A girl in my Advanced Higher Graphic Communication class is drawing this as a 3D model in Autocad Inventor. It is incredibly complex. I take pictures of their chosen objects so that they can remember how all the bits fit together. I might blip the end result of this when she is finished.

I must ask her how she did it too!
