Compressed air engine

This is a compressed air engine I designed in Solidworks. I made it because I was inspired to figure out how steam engines worked after taking an intro to thermodynamics class. Videos of it running and how the inside works can be found on my youtube channel:

Also note you will need some extra parts for the build:


-Wooden base of some sort.

-Small wooden block about the engine's height - it needs to be in line horizontally with the flywheel otherwise the piston will jam against the casing.

-M2 and M3 screws - four M3 and six M2.

-624ZZ bearing. (commonly used in 3d printers for belt pulleys)

-Traxxas oilite bushings: I use these for the airtight(ish) seals for the moving parts:
