Product Description
This is a small model of the saddle surface z=x^2-y^2 restricted to a circular domain. If you've ever wanted to have a Steel Pringle, now is your chance!
Design notes:
The surface was created with Mathematica, using the code Plot3D[.1(x^2-x^2),{x,-5,5},{y,-5,5}, PlotPoints->40, PlotTheme->"ThickSurface"], then exported to STL.
