40mm fan blade replacement
thingiverse
The original fan blade replacement was a bit cumbersome to me, so I modified the blade assembly in order to have a complete replacement of the blade assembly, including the axle support. From the old fan blade assembly I keep the magnet and the axle and the two O'rings. The axle socket is 2.1mm wide, so the axle fits tight, I just add a drop of superglue at the bottom. Then there is no need to center, etc.
