Frequently Asked Questions
Q: Are all 105 plastic gear pieces compatible with each other?
A: Yes! All components in this DIY gear set share a standardized 0.5M modulus, which means they can be freely mixed, matched, and combined to create custom gear trains, gearboxes, and power transmission assemblies.
Q: What material are the gears made from, and is it durable enough for motorized models?
A: The gears are made from POM (Polyoxymethylene) plastic, a high-performance engineering thermoplastic known for its low friction, good wear resistance, and dimensional stability. It is well-suited for light-duty motorized models, robotics prototypes, and mechanical DIY projects.
Q: Can beginners use this gear set for school or hobbyist projects?
A: Absolutely. This plastic gear and pulley set is designed to be accessible for students and hobbyists while still offering enough variety for advanced makers. The assorted aperture sizes (0.8–3 mm and beyond) and multiple gear types make it a versatile starting point for learning mechanical engineering concepts or building custom DIY gearbox models.
