The file 'Steam / Compressed Air Engine 3D Printer Model' is (stl) file type, size is 25.1MB.
This is just something I made for fun. It's a locomotive style reciprocating (1/2 stroke cycle) steam engine.
I didn't originally design it to run, just be a model. But after some careful sanding and filing, as well as liberal amounts of graphite, it does run on compressed air.
I may modify it at some point. ...Give it a larger piston and larger valve ports.
Here's a quick video if you want to see it run (Sorry about the aspect ratio).
