60 mm impeller less pitch more rpm free Free 3D model

This impeller is less agressive and does 0.75 rotations over the 45mm lenght and is for the small jet unit that featured on my youtube channel Daniel Kuizinas . Print this upside down with a brim i got away without support material but it is pushing the limits! I think it should be printed at 100% infill if it is going to be working hard , it has a recess suitable for a m8 nut which is 13mm across the flats then room for another nut behind to lock it you will need to use another nut in front unless using a spacer tube. The outside will need to be sanded to to fit tightly in the flow corrector as shown in the video
