Cement Mixer Motor Cooling Fan

I found a free cement mixer on OfferUp. The motor was full of water and the fan to cool off the motor was broken. All the fan blades cracked and fell off. I modeled up the new fan in Fusion 360.

First print the thin sleeve cracked. Switching to a different design with a through bolt (I will need to drill a hole through the shaft. First fan was great on the dimensions. 0.2mm shrink factor worked great.
