This hyperboloid is a type of quadric surface- or a type of mathematical surface in three dimensions. I made this object to understand more about hyperboloids for my multivariable calculus class. This object demonstrates that every point on a hyperboloid has exactly two lines crossing through it that also lie on the hyperboloid. It also shows that a hyperboloid can be created by rotating a line around a skew line.This was designed in Autodesk Inventor and printed on a MakerBot Thing-O-Matic.
