Compressed Air Engine

Print at 15% infill or higher I used PLA. Most parts will need a sanding to make them as smooth as possible.You will need a 0.312 in diameter dowel rod with a keyway at the end connecting to “crankshaft”. This connects the flywheel to the crankshaft.You will also need a small O Ring inside of the cylinder. Along with a 6mm Airsoft BB to act as the ball valve.You will also need a small metal pin connecting the connecting rod to the crankshaft halfs.See the engine running here:
