A full, not to scale model of the USS Baltimore.

-----Edit 3-----
Included some color as well as accurate 8' gun models. American flag on #2 turret as well as flying from 2nd mast, along with two star flag. If you would like a different or custom second flag, please message me. Model found under name CA-68 Slate grey USA flag, RAMD.obj

Using 3d builder on windows, I was able to download an .stl file with the most recent hull and most recent superstructure. I plan on revising the 8' guns to be more historically accurate, as well as adding color. Look to the file called Balti final for the latest version.
-----Edit 1-----
I included a historically accurate hull, along with a superstructure that matches with the hull. Neither Tinkercad nor Thingiverse could successfully download an .stl with both together, so centering both, making sure that the hull is long-ways, rotated to sit flat and max sized, and the superstructure is at 12mm in the x direction and 5.4mm in the Y direction should ensure a proper print of both with the proper hull and fixed Bofors mounts and cranes.

Summary from Wikipedia:
"The Baltimore-class cruiser was a large class of heavy cruisers in the United States Navy commissioned during or shortly after World War II. Fourteen Baltimores were completed, more than any other class of heavy cruiser, along with three ships of the Oregon City class sub-class. Fast and heavily armed, the Baltimore cruisers were mainly used in World War II to protect the fast aircraft carriers in battle groups from air attack. Additionally, their 8-inch (203 mm) main guns and secondary 5-inch (127 mm) guns were regularly used to bombard land targets in support of amphibious landings. After the war, only six Baltimores (St Paul, Macon, Toledo, Columbus, Bremerton, and Helena) and two Oregon City-class ships (Albany and Rochester) remained in service, while the rest were moved to the reserve fleet. However, all ships except Boston, Canberra, Chicago and Fall River were reactivated for the Korean War. Except for St Paul, all the ships retaining all-gun configurations had very short (18 years or less) service lives, and by 1971 were decommissioned, and started showing up in the scrap-sale lists. However, four Baltimore-class cruisers were refitted and converted into some of the first guided missile cruisers in the world, becoming two of the three Albany-class and two Boston-class cruisers. The last of these was decommissioned in 1980, with the Chicago lasting until 1991 in reserve. No example of the Baltimore class still exists."
