Four Speed Gearbox Model Description A functional four speed gearbox model produced by 3D printing in PLA plastic. Designed for demonstration, prototyping, and hobby use, this model reproduces the core layout and operation of a manual four speed gearbox so users can study gear ratios, shaft arrangement, and shifting mechanics. Key benefits Clear demonstration of gearbox mechanics: Shows four distinct gear ratios and the physical interaction between gears and shafts, making it ideal for learning and teaching. Rapid prototyping and iteration: 3D printed PLA construction allows quick replacement or modification of parts to test alternate geometries and fit. Visual and hands on learning: Transparent access to moving parts helps students, designers, and hobbyists observe gear engagement, tolerances, and lever action. Low friction functional operation: Accurately printed gear teeth and alignment improve mesh consistency for repeatable demonstrations. Easy integration into projects: Compact form and common mounting points simplify inclusion in model builds and classroom rigs. Important attributes Function: Four speed gearbox model that demonstrates gear selection and transmission of rotational motion across multiple ratios. Material: PLA plastic produced by 3D printing for consistent geometry and easy . Size and form factor: Compact model suitable for tabletop demonstration and small prototypes. Designed for visibility of internal components. Performance: Reproducible gear engagement and reliable manual shifting between gears for educational and prototyping tasks. Assembly and maintenance: Delivered as assembled or as kits depending on . Parts can be replaced or reprinted to refine fit or test changes. Typical applications Classroom demonstration: Use in engineering, physics, or technical courses to teach gear ratios, torque transfer, and basic transmission concepts. Design and prototyping: Validate gear layouts and shifting sequences before committing to metal or production tooling. Modify CAD and reprint updated parts quickly. Hobby and model builds: Integrate into scale models, small drivetrains, or display units where a working gearbox illustration improves understanding or realism. What you will receive A four speed gearbox model printed in PLA plastic, with moving gears and shift mechanism ready for demonstration. Model files or replacement parts can be reprinted as needed to support iteration and . Notes This product is intended for educational, demonstration, and prototyping use. PLA material and 3D printed parts are not intended for heavy industrial loads or continuous torque applications.
