40mm fan blades
thingiverse
After crashing the extruder against the end-stop and destroying two 40mm fans, I decided to design a replacement for the broken blades, thereby saving 5€ in the process. It's always wise to have spare parts on hand when unexpected repairs become necessary for proper printer operation. I adapted the dimensions of the fan blades designed by kj6epl from Thingiverse (thing:36223) except for the outer diameter. My replacement fans feature a 36mm outer diameter, whereas kj6epl's original design uses a 0.7in or 35.56mm diameter. This same detailed repair instruction can also be found on Thingiverse. Given that our dimensions match, it's logical to assume that these new blades will fit all 40mm fans.
