Customizable Laptop Fan Blade Replacement

Customizable blade replacement for repairing centrifugal fans with broken blades on laptops, 3D printers, and anything else.

How to determine sizing:
* Cut all the blades off of the damaged fan leaving short (~1mm) and evenly sized stubs. Using flush cutters to do this will ensure that all the stubs are the same length.
* Measure the diameter of the rotor with blade stubs included.
* Change the hub inner diameter in the customizer to match the measured diameter in order to achieve a tight press fit. You will need to increase this slightly if your printer typically prints holes too small.

Tips:
* For best results, try to match the blade length and blade count of the original fan.
* The blades should be as thin as possible while still being rigid for the highest efficiency. 0.8mm thick blades work well with PLA. I tested a 54mm diameter PLA impeller with 0.8mm thick blades and it exploded at around 19000 RPM. The vast majority of standard centrifugal fans run well below this s
