Note: In class we were encouraged to go online to find models that we could follow to learn.
Credit goes to 3d Content Central for the use of four of their models. I borrowed and then modified the propeller for my model airplane, the auger helix for my meat grinder, some modeling techniques for my golf club head, and the box for my airbrush in box.
I also want to give credit to my friend Javad Mombayni for his much appreciated help with my magnifying glass.
