About 20 Exchange Place
20 Exchange Place is a skyscraper in Lower Manhattan's Financial District, in New York City. It was first known as the City Bank–Farmers Trust Building. The City Bank–Farmers Trust Company, a predecessor of Citigroup, had Cross & Cross design it as its headquarters, and it was completed in 1931. It rises about 226 m (741 ft) with 57 usable stories. On completion it ranked among the tallest buildings in the city and was the tallest stone-clad building in the world. Because of the Great Depression, the plan to make it the world's tallest building was scaled back.
The facade is almost entirely white Rockwood Alabama stone, with Mohegan granite on the first story, over a steel superstructure. The base fills an entire city block and is shaped like a keystone. The tower above the 21st floor has an octagonal plan, its four chamfered corners alternating with four longer sides, and it is offset from the base. British sculptor David Evans designed much of the decoration on the lower stories. Eleven granite medallions surround the round arch of the main entrance on Exchange Place, standing for the countries in which the bank operated offices.
It was constructed in 1930 and 1931 for the Farmers' Loan and Trust Company and the National City Bank of New York, which had just merged, and it stayed their headquarters until 1956. Metro Loft Management turned the 16th through 57th floors into residences in the 1990s. In 1996 the city's Landmarks Preservation Commission made it a city landmark, and it also contributes to the Wall Street Historic District.

- A slim octagonal tower
- The tower is narrow for its height. Printing slowly helps a tall, slim shaft, and layers of 0.12 to 0.16 mm keep its chamfered corners crisp.
- Small arches at the crown
- A ring of small arches sits near the top of the tower. Print friendly adapts them to the print scale; Full detail keeps them, which suits a larger print or a fine nozzle.
- One piece with the ground
- 20 Exchange Place 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. 20 Exchange Place 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.
