Turbine/Impeller
thingiverse
The parametric turbine model, designed in OpenSCAD, offers adjustable features. Created more for aesthetic appeal than scientific precision, it can spin efficiently when blown into or with a balloon at its inlet. A brief video demonstration is available here: http://www.flickr.com/photos/53725866@N07/5417888910/. To assemble, print the 3 components and insert a 3mm filament as an axle; some cleanup or clearance adjustments might be necessary. The housing_space variable determines clearance between the wheel and housing. While it scales well, other settings may require testing.
