Hello, i made a remix of a Rotary engine i found here on thingiverse. I redesigned the backhousing and crankshaft to use a stepper motor, as i wanted to show the true path that the rotor makes inside the housing.
I also made a enclosure for the circuit, and some buttons as well.
To end the project i mounted the model on a wood sheet, with some identification boards.
All files are available to download, as well as the circuit board and stepper motor used for this project.

To power this circuit i used a generic usb cable, and soldered the positive and negative wire respectively.

You can check how i made it and how it works in this vídeo.
