this is what i have so far, bit i cant get it water tight to print, too many faces, also the parts connecting to the axle is so becomes to thin it will not be sturdy
entire axle will be 80mm high and blades 3mm thick

also i just want the axle no flat part in the middel, it must look like the golden spiral

any help will be apreciated
thank you
