A centrifugal Cooling fan. was made to replace one for a 100cc Scooter/moped.
the walls of the blades Ive made a bit thicker for the current vision to increase strength
as it needed to survive High Rpm and resist warping from heat.
depending on use case should be printed in ABS or similar material for best strength. Pla is strong enough just doesn't withstand heat.

I printed it with 3 walls thick and 25% infill (ABS). still Holding up.
you may need to allow bridging in your slicer settings for best results with the top support ring.

If you need the mount holes relocated let me know i can alter that for you.
