Miniature 3Blade Plastic Fan Blades for Motor Experiments, 10 Pack Compact, lightweight fan blades designed for student experiments, DIY projects, and small model applications. Each blade has a precise 1.95 mm inner hole for a secure fit on miniature motor shafts. Made of flexible plastic with a smooth finish to ease handling and assembly. Key features and benefits Precise fit: 1.95 mm inner bore ensures a tight connection to miniature motor shafts for stable rotation. Compact size: 5.20 x 5.00 x 1.00 cm makes the blades easy to handle and suitable for smallscale projects and classroom use. Threeblade design: Balanced 3blade shape works well for basic airflow demonstrations and model propulsion experiments. Durable, flexible material: Plastic construction allows slight bending for alignment and simple adjustments during assembly. Smooth workmanship: Clean edges and no burrs for comfortable handling and safer classroom use. Versatile learning tool: Supports handson learning in physics, electronics, and engineering projects while encouraging practical skill development. Package contents and specifications Quantity: 10 tiny fan blades Color: Skyblue Material: Plastic Size: 5.20 x 5.00 x 1.00 cm Inner hole diameter: 1.95 mm Blade count per fan: 3 leaves Typical applications School science experiments: Use with classroom miniature motors to demonstrate concepts such as rotational motion, thrust, and airflow. Model making and RC projects: Suitable as small propellers for model boats, gliders, or experimental vehicles driven by micro motors. DIY prototypes and hobby electronics: Quick to install on small DC or hobby motors for cooling demonstrations, airflow testing, or simple mechanical builds. Compatibility and tips Designed to fit miniature motor shafts with an approximately 1.95 mm diameter. Confirm shaft size before installation for results. Pressfit onto the motor shaft and secure if needed using a small set screw or adhesive, depending on the application and rotational speed. Handle gently when fitting to avoid bending; the flexible plastic aids alignment but is not intended for speed or heavyload use. This pack provides multiple spare blades for classroom sets, project kits, or hobby workshops, offering a practical option for repeating experiments and building several prototypes.
