Ellipsoid with Corner Cutout

This is the model of a 3D Ellipsoid. This is useful to help tangibly demonstrate what the equation of a an ellipsoid [(x^2/a^2)+(y^2/b^2)+(z^2/c^2)=1] looks like in 3D. This model has a corner cut out of it to better help individuals visualize the ellipses which form the ellipsoid.
