3D Cone with Spherical Top

This is the model of a 3D cone with a spherical top (hollowed out). This is useful to help tangibly demonstrate what the equation of a such a shape (z^2 = x^2 + y^2) looks like in 3D. This model has a small air hole poked out of its tip so that it can be printed in a resin printer, such as the Formlabs printers, preventing resin from being trapped inside the model.
