Conic Sections

This is a set of conic sections for class room use. There is also a connector for joining two sets of sections so that both halves of the hyperbola can be illustrated.

Conic sections are pretty standard, but I used the approximate sizes and the idea for dowels from karlcrosby's design. The major change is that the hyperbola is from a slice perpendicular to the xy plane to allow for both halves to be illustrated.
