    Curious. Could you 3d print a propeller or does it demand some sort of higher quality manufacturing process? For a DIY drone project slapping some toroidal propellers just to test it out seems doable.

      It’s been done a lot, but its kinda pointless as any noise improvements from the shape are obliterated by the bad surface finish.
