Paraboloid - with formula

This models shows the paraboloid z=x^2+y^2 with its formula. There is a second .stl file giving the surface without a formula.

This model was designed and printed by my WLU summer research student Emily Jaekle ('16). See http://mathvis.academic.wlu.edu/2015/07/20/quadratic-surfaces-paraboloids/ for more information.
