This is a project I designed just because I wanted to design something in fusion 360, I also wanted to learn a bit about the whole piston assembly in an engine. In order to print this you need to rotate all case pieces, the piston pin, the piston pin lock, and the cylinder 83.9 degrees on the y axes, then you rotate the piston head 270 degrees on the Y. the cam shaft gets turned 90 degrees on the x axes, the support cam shaft gets turned 270 on the x. this should be every thing, I know it seems like a lot but it only takes a couple of seconds I just didn't want people to have to troubleshoot it themselves. I tried to do all this in fusion 360 but I couldn't. This thing is super tiny for some reason in my slicer, if it is tiny for you scale it to 600% and it will be good. I put a lot of work into this project so I figured I would upload it to Thingiverse. it is super cool once it is done and is a good demonstration.
PS. you will need 2 case upper pieces
