Working Twin Cylinder Air Engine

Please note that this is an older version and not recommended. The better version of this engine is available at https://www.thingiverse.com/thing:4577156.

This is working compressed air engine that is fully 3D printed and does not require any hardware. The design is based on thing:576482 and has added functionality. This engine can operate from compressed air and can deliver substantial power via integrated Gear on flywheel.

Most likely I will continue development of this engine and add power modules and accessories. Let me know what would be good development for this engine.

The engine design process and tests are available in https://youtu.be/ciSbL8yVtwA and the build process https://youtu.be/a1t0a2YkKbk .
