The Hand Crank Gear Fan is a functional mechanical model designed as a kinetic desk toy powered entirely by a manual crank mechanism.

Turning the crank activates a gear transmission system that rotates the fan blades smoothly, demonstrating basic mechanical motion without the need for motors, electronics, or batteries.

This model works as both a mechanical learning tool and a decorative kinetic gadget, making it ideal for STEM demonstrations, engineering education, and maker projects.

Ideal for:

• STEM education and mechanical demonstrations• engineering learning projects• kinetic desk toys and gadgets• makerspace and workshop displays• hands-on mechanical learning

3D Printing

The model is optimized for FDM 3D printing.

• simple mechanical gear transmission• modular design for easy assembly• scalable to different sizes• suitable for PLA and similar materials

Included file formats

• STL• 3MF• AMF

Perfect for creators interested in mechanical engineering models, kinetic toys, and educational 3D prints.
