Run by simply blowing air into it.

Some parts need supports, such as Cylinder_Back_Lid and Valve_Lid_6mm. After printing, cut away the brims from Cylinder_Ring parts. Assembly instructions are coming soon. In short: - Cut off a glove finger tip - Pull it onto a Cylinder_Ring (use Helper_Finger to leave enough height) - Connect a Piston to it with two Washers - Clamp the Cylinder_Ring between Cylinder_Plate and Cylinder_Lid - Clip them with Helper_Clamp so they won't fall apart at once - Bolt them together to Plate_Top - Repeat for the other 2 cylinders - Insert the Crank with 2 Washers - Fix it in place with Frame_Bottom - Bolt all parts together - Put the Valve_Inner in place - Bolt the Valve_Lid into place - The engine should be running!
