A saddle surface is one of the few things I think is really worth 3D printing for Calculus students. There’s something important able to feel the two competing curvatures with your actual hands, instead of just looking at a picture. Since I always like to use the simplest design tools possible, this is a model that I export from Mathematica and then process in the much easier to use design software Tinkercad… // Hacktastic
