My 3D tool is a space telescope. You use this tool in space to see all the planets that were too far to see on Earth. This tool solves the problem of not being able find all planets and helps astronauts see what else is in space that has yet to be discovered. The structure of this telescope is the shape of a regular telescope. A cone without the point. It would be desired and used by astronauts to see all of the farther away planets that are in space.
