A detailed printable model of the manned moonrocket from the French 50s comics The Adventures Of Tintin, especially the Destination Moon and Explorers On The Moon books.
The rocket is about 55 meters tall and the model is full scale but can be scaled down and all features will print well even in a small model.
The rocket in the comics was nuclear powered, somewhat justifying the single stage design and while not perfectly accurate it was, for the time a rather detailed and forward looking vision of the future and has become kind of an icon among both comic and spaceflight enthusiasts.
