Finally after many years since watching the Starblazers cartoon series a kid, I now have a model smilar to the Argo (aka Spaceship Yamato)This model is sized at about half a meter long.  You can print at smaller size but the details might get lost.  The smaller turrets are also difficult to make at reduced scale.Included in the files are a complete stl which you can slice anyway you wish, and a set of separate stls that I used to print mine.  This is handy for some of the finer details or direction of printing.
