3D Cone with Spherical Top

thingiverse

This is a precise replica of a three-dimensional cone with a spherical cap on top, hollowed out to perfection. It serves as an invaluable tool for visually illustrating the equation of this specific shape (z^2 = x^2 + y^2) in three dimensions. This exact replica features a tiny air vent drilled into its apex, allowing it to be printed seamlessly in a resin printer like the Formlabs model, thereby preventing any resin from becoming trapped within the model.
