thingiverse
A little engine that I made, I don't have an air compressor so its running off a motor but its pumping air, I think it will run on air, I got it to turn over a few time by blowing.
Parts print with no tolerance so some sanding is required on the pistons, this is to allow them to be sanded smooth
The small Piston needs to be offset by 90 Degrees on the shaft.
