Rotary Vane Air Engine

This print requires little sanding on the Vanes for the rotor, but the sanding is only necessary at the smaller print size it come's in! If you scale it up it should fit a lot better without sanding! The vanes should basically fall out of the rotor without the rotor being in the housing, the vanes that come with the rotor itself don't work all that well so there is a file with a new design for the vanes! no springs, no screws, no bearings all you need is the printer and some super glue for the lid of the housing!
