Steam Engine

Here is my first upload. I had to make this for school It is a 2 cylinder spool valve engine it should run but if it doesn't i can make changes to it. ill get some printed pictures as soon as i can. I am probably going to simplify this to use less plastic because right not it is a bit excessive for just a model(I am making a vehicle that moves with compressed air that runs along a track. watch for parts for that e.g. transmission differential frame, the like.). If you have any questions just leave them in the comments
