Radial Impeller - Prop Adapter Mount

thingiverse

I had some issues to get the impeller properly centered and balanced. At high speeds even a slight imbalance or off-centre will result in higher noise and reduction in efficiency. I merged piece 01 and 02 and also modified the center to fit a propeller adapter. The prop adapter I use is M6 for 5mm motor axle. The impeller is also printed in one piece so support material is required. However, printing in one piece will make it perfectly centered.
