Drawing/Sketching Forms

I needed some sketching forms for a class I'm writing and I saw some for sale on line for $31. They were each about 2 inches tall and I realized that I could totally make a set of these. I haven't tried to print these out yet, but I am assuming the complex forms and the sphere will need supports. I don't know about the icosphere or icohedron. I will update once I've printed the set next week.
