Dopp Industries 1C Pneumatic Engine

This is my first model upload. This is theoretically a working pneumatic engine. I say theoretically because I do not have an air compressor to test it on. If you print the model and test it, let me know if it works, if it doesn’t try to figure out the problem and dm me so I can try to fix the model. It works if you lube all moving parts with a low weight wet lube and or dry lube. (I used baby oil and graphite because that is what I had on hand.) It is assembled with m3 and m2 screws. Use ¼-20 nuts for the flywheel. You need to cut one screw for the piston wrist pin.
