Extruder

An extruder is a tool that can take a material, like play-doh, and push it out of a small hole at the end. Just like how you might push play-doh through a shape maker to create different shapes, an extruder can make a long string or tube of the material instead. This can be really helpful if you want to make things like wires for electronics, or even spaghetti noodles! The extruder can also work with other materials like plastic or metal, and is often used in factories to create different shapes or parts for things like cars or machines. So, think of an extruder as a machine that can push materials out of a small hole to make different shapes or parts.
