The file 'Pachacuti Mk.1.1 FF Rocket Engine 3D Printer Model' is (PDF,STL) file type, size is 28.9MB.
I made this as a challenge for myself, it's the first rendition of a scale model of a full flow methane oxygen rocket engine that I conceived myself. I used pre existing engines as guides to build it, it's largely grounded in the SSME and BE-4 engines.
The model has a fully built interior with modelled turbopumps and injector systems (I can upload the various components if there is an interest in them, although I should mention there are over 500 individual components but I could upload the main ones and the primary sub assemblies if it's requested).
One of the reasons I started this project was because I felt that it would be an incredible idea to have a model rocket motor in the reach of any student interested in aeronautical engineering.
There's a thread that I put up about the engine here: http://forum.nasaspaceflight.com/index.php?topic=39200.msg1468297#msg1468297 There's also a lot of the designs as sheets there as well, which is helpful to demonstrate the inner workings of the engine.
