If you want a car, but your parents aren't ready for that, you can make your own. You can start from the small - a gear, for example. It is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth also called cogs, which mesh with another toothed part to transmit torque and speed. It's used not only in cars or machines but also in clocks, as big clock towers, so small ones. Minimal cursor with Gear.
