Customizable Laptop Fan Blade Replacement

Customizable blade replacement for repairing broken blades on laptops, 3D printers, and other devices. To determine the correct size: Cut off all damaged fan blades, leaving short (about 1mm) stubs. Use flush cutters to ensure all stubs are equal in length. Measure the rotor diameter with blade stubs attached. Adjust the hub inner diameter in the customizer to match the measured diameter for a tight press fit. Tips: For optimal results, replicate the original fan's blade length and count. Blades should be as thin as possible while remaining rigid for maximum efficiency. 0.8mm thick blades work well with PLA. I tested a 54mm PLA impeller with 0.8mm blades and it spun at around 19,000 RPM before failing. Most standard centrifugal fans run below this speed. Balancing is usually not an issue for general use based on my experience.
