About the United Nations Headquarters
New York's United Nations headquarters sits in Turtle Bay, in Midtown Manhattan, on grounds of 6.9 to 7.3 ha (17 to 18 acres) between 42nd and 48th Streets, with First Avenue on one side and the East River on the other. The complex was finished in 1952 and includes the Secretariat, the Conference Building, the General Assembly Building and the Dag Hammarskjöld Library. Among the principal organs seated here are the Security Council and the General Assembly. The International Court of Justice is not, and sits in The Hague.
Wallace Harrison led the board of architects that designed the complex. Oscar Niemeyer and Le Corbusier developed the final projects, and Harrison & Abramovitz built it. The UN chose not to hold a competition and instead commissioned a multinational team of leading architects, and the design process formally began in February 1947. The site beside the East River was bought from the developer William Zeckendorf Sr.; Nelson Rockefeller had purchased an option on the land, and in December 1946 the site was donated to the UN.
Under a treaty with the United States government, the land the UN occupies, along with spaces in buildings it rents, is technically extraterritorial and administered solely by the UN. The UN, for its part, acknowledges most local, state and federal laws in return for police, fire protection and other local services. None of the 15 UN specialized agencies, such as UNESCO, has its offices at the headquarters, though some autonomous bodies, such as UNICEF, are based there.
How it prints
Make this print opens the generator on a 600 m square around the landmark. Buildings print at close to true scale, so the landmark grows with the print size.

|---|---|---|
| 160 mm default | 43 mm | 1:3,750 |
| 200 mm | 53 mm | 1:3,000 |

- Tall slab, fine window grid
- The tallest block is a thin slab covered in a fine grid of windows. Print slowly, and use 0.12–0.16 mm layers; Full detail keeps the window grid on a larger print.
- Low halls and a shallow dome
- Long, low blocks and a shallow dome sit beside the slab. Smooth shapes like these look cleaner with thin layers, and a larger print size keeps their edges sharp.
- One piece with the ground
- The United Nations Headquarters is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
- Pick the detail for your nozzle
- In the Buildings settings, set Landmark detail to Print friendly to adapt thin parts and small details to the print scale. Full detail keeps every modeled feature, for larger prints or a finer nozzle.
- Colors
- Buildings, roads, water and ground arrive as separate filament slots in the 3MF. The United Nations Headquarters takes the building color.
- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
