About this model

Single rotor Wankel rotor engine for display. This is derived from the Grabcad model by Ravi Yadav ( and converted into a 3d printable option. It will require some gluing and a piece of plexi-glass for the back. You can printout a back plate but i didn't like having the back covered. Enjoy UPDATE added a back plate just in case.
