📦 Basic Information
- Purpose: Cooling fan blades compatible with small DC motors, suitable for fan replacement or upgrade in scenarios such as 3D printers, DIY ventilation equipment, and miniature heat dissipation modules.
- Key Parameters: Center mounting hole diameter 2.50 mm, 4 blades, overall design balances airflow and low noise performance.
- Design Style: Streamlined blades + lightweight structure, compatible with most 5V/12V micro motors.
✨ Design Features
- Five-Blade Airflow Optimization: Compared to traditional three-blade fans, the five-blade design provides smoother airflow, lower operating noise, and more even heat dissipation efficiency.
- Streamlined Blades: The blades feature a streamlined profile with rounded transitions, effectively reducing air resistance and increasing airflow at a given rotational speed.
- Reinforced Center Structure: The area around the central shaft hole is thickened and reinforced, preventing loosening or breakage after installation, making it suitable for long-term high-frequency operation.
- Lightweight Design: Blade wall thickness and infill rate are optimized to ensure strength while reducing motor load.
🛠️ Installation Instructions
- Confirm your motor shaft diameter is 2.5 mm, or adapt it to a slightly smaller shaft diameter using heat shrink tubing or a small amount of glue.
- Insert the blade's center hole directly onto the motor shaft, ensuring it is fully seated.
- If there is a gap in the shaft diameter, wrap a small amount of tape or apply anaerobic adhesive between the shaft and the hole for reinforcement.
🎯 Applicable Scenarios
- 3D printer extruder / hotbed cooling fan modification
- DIY small desktop ventilation equipment
- Heat dissipation modules for miniature water pumps and small motors
- Ventilation / heat dissipation modules in maker projects
