how many mm is the connector to the shaft at the bottom?

Question: How do you go about designing something like this? I'm currently trying to design and print a vawt myself, but it is with 3 straight NACA0021 blades. Would love to know how to make them twist like you did.

Hi, this is not my design but a remix of http://www.thingiverse.com/thing:10055

However, I use rhinoceros modeling software and I think is good for you define the curves of sweeps between the top and the bottom of external blade profile and then use sweep two rail command using the curves as rails and the naca profiles as sections; let me know if it works

now that's sharp, looks like it should push nicely. are you going to make the rest 3d as well? or is it going onto another in need of this?

Yes, you must to stack more equal pieces, in the photo I printed and overlap only two (adding the cap on the top).
