The only thing I had trouble with these intros into 3D printing were the controls. They aren't the greatest of user friendly controls but I managed to overcome this technical difficulty. After a while the controls became almost second nature and I was able to move and shape objects with ease. What I found the most successful about the intros was how simple objects could be used to make rather impressive designs. It almost made me want to go on to make more projects aside for the intros. One thing I would like to make would be miniatures based off movies, games, and pop culture. I think it would be fun to 3D print a knife maybe if I can manage it.
