To keep a long story short I'm in the process of trying to reverse engineer the .factory format this program called Simplify3D which is a 3D printing software slicer. I love the software but everything is closed source and I want a way for me to somewhat generate these files myself for automation purposes.

I did a small tint STL file into the software and exported this. If anyone knows anything related to what possible encryption was used and compression would be helpful. I tried looking at it myself and I feel some sort of encryption is used for sure as when I changed one parameter a lot of data seemed to change. Not sure as far as compression goes though.
