Wankel Rotary Engine

thingiverse

This remix * combines the main rotor with the larger tooth outer gear (no more gluing) * increases the size of the mounting holes for the back-plate (less likely to snap) * replaces the round handle fitment to the engine shaft with a hexagonal one (no more slipping) * adds an adapter for connecting a power drill to the model in place of the handle The model should not require any gluing, unless you feel the press fit is not enough. I have made the handle to shaft fitment slightly loose so the handle can be removed for easy disassembly.
