This is the biggest working 3D printed engine model in the world. It is also my most complex and time consuming project ever. Originally, the engine was designed to be printed at a scale of 1:75. But in an effort of pure madness, I started printing every part scaled up by 200%. I spent way more time on this project than I ever anticipated. But seeing it finally running makes me extremely happy and proud.
