I gave the prop a try with the same crappy filament and ran into some issues. (I had a feeling printing this would not that easy or straight forward becuase of the angles of the blades)

The blades are so thin that the edges are tending to warp when printed in PLA. (Things would probably be a lot easier with a duel nozzle printer that could print with water soluble supports.)

I could probably heat the edges up and bend them back to the correct positions if I wanted to but I thought I'd try a different material. (PLA isn't the best choice for outside items anyway.)

I next tried to print a prop in PETG and while it came out a lot better....

... the blades are way too flexible.

At this point I decided to make the blades thicker and see if that would help with the printing. I really don't have the CAD skills to redesign the angles on these blades so for now I basically just stacked several copies of them to make them thicker. The weird edge details will be ignored by the slicing software because they are so thin.

I printed this thicker version in both PLA and PETG and they came out a lot better. (In these pictures I rough sanded the PETG one but not the PLA one yet.)

I don't know if it will affect the thrust out put of the prop but it definitely came out better being thicker.
The PETG one is still a bit flexible so I'm going to test it first with the PLA version.

Next it's on to printing the nozzle which might present some challenges but I think I know how to get around them..... We'll see.
