Mini inline 4 cylinders engine, with Fully functional moving pistons, pistons moving up and down when you are rotating the gear. I made it without piston rods and crankshaft to avoid complications in assembling so its optimized for easy printing with no supports required. i am using camshaft instead. Easy to print, easy to assembly. Great for car fans. Material: PLA (Silver, Gunmetal, or Metallic colors look best).

Assembly notes:
