Not the most efficient vawt but it is fully 3d printed and it works with 3d printed bearings. Use 16mm PVC tubes or with any other diameter pipe (see openscad file for full hack).

OpenSCAD files available. 

I'm using the parametric printed bearing library: https://www.thingiverse.com/thing:3112100
