5-Blade Impeller
This is a custom-designed 5-blade fan impeller optimized for 20,000 RPM inline dusters and small ducted fans. The sweeping blade geometry is specifically modeled to maximize airflow and minimize motor drag. It mounts quickly and securely to standard small 3V DC motors using a tight 2 mm press-fit hub.
Recommended Print Settings
To get the best aerodynamic performance and structural strength, please reference the following slicer settings:
Layer Height: 0.12 mm or 0.16 mm (This provides the cleanest resolution for the curved airfoils).
Wall Ordering: Print Inner then Outer walls to improve the surface quality of the overhangs.
Adhesion: A Brim is highly recommended to keep the fan securely anchored to the bed during printing.
Supports: None needed the are pre-designed supports that support the fan blades during printing, and easily snap off.
Post-Processing Tip
Sanding: Lightly sanding the fan blades after printing smooths out the layer lines. This small step might noticeably reduce aerodynamic noise and improve overall airflow performance!
