A set of containers designed to be able to fill with water, sand, or something similar and pour between containers to compare volume. The diameter of the cylinder and sphere and base of the cone are the same, which is the same as the length of the cube. The cone and sphere have bases to hold them upright, and the sphere has a lip to pour through to avoid making a mess if pouring a liquid.

Designed to print without supports. The sphere may look a little messy from overhang, but the shell being 2mm thick worked for me, using PLA and the cooling fan turned on.
