Got a DIY project in mind? These plastic gears from MECCANIXITY are a game-changer! You get 40 pieces of sturdy white plastic gears, each with 24 teeth and a module of 0.5. They’re perfect for all sorts of builds – think RC cars, DIY robots, windmill models, or even school science projects to show how gear ratios work. The specs: outside diameter is 13mm (about 0.51 inches), shaft diameter is 2mm (0.08 inches), and they’re 5mm thick. They’re lightweight yet durable, so they can handle the action without wearing out quickly. The reduction gear design helps you fine-tune speed and torque, which is super handy for making your RC car zippier or your robot stronger. Installation is a breeze – just slide them onto a 2mm shaft. A quick tip: double-check the size before you order to make sure they fit your project. Whether you’re a hobbyist, a student, or just love tinkering, these gears are a must-have for your toolkit!
