Here is an image of the first Maya polygonal tutorial: Simply titled hammer!

For the next model which supposed to be a nurbs model I forgot what it was supposed to be so I just made my own nurbs model. Both tubes were modelled from a profile extruded along a path. They were both slightly modified afterwards to fix any interpenetraction of the transparent tube running around the larger white one. Then parts of each tube were expanded to give some parts a larger volume than others. The background is a nurbs plane modeled to mold around the profile of both tubes using the sculpt surfaces tool

If anyone would like the model files I'll happily send them to you.
