Jet Turbine Fan Fidget Spinner

*UPDATE 15JUL2017: I redesigned the spinner so it prints cleaner now. The blades are uniform thickness so your slicer hopefully won't start and stop mid blade*

I designed this to resemble the "Fan" section of a jet turbine engine. Simply blowing on it will spin it.

The fan is directional. Due to the curve of the blades, blowing on it from one side vs the other will make it spin much faster. Just holding it to the air vent in your car with the blower on high will spin it a lot. You can easily see the speed difference depending on the direction. If you print this the way it's facing in the STL, the side that is facing up while on the build plate, is the side that you should direct the air, to make it spin the fastest.

*Use my Spinner Press to help insert the bearings. http://www.thingiverse.com/thing:2275122*

I printed mine without supports and it came out pretty well. You can try it with support as it should be very easy to remove the support in this case.
