About 99 John Street
99 John Street began life under the name Insurance Company of North America Building. The tower stands on John Street, in Manhattan's Financial District, New York City, and its Art Deco design came from Shreve, Lamb & Harmon, the firm behind the Empire State Building, finished two years earlier.
The main block is 28 stories and 103 meters (338 feet) tall. Chamfered corners, granite and limestone decoration, and a massing of five setbacks that taper to a two-story penthouse define its exterior. Gold Street has a shorter four-story annex, added after the main building. The structure is steel-framed and rests on 434 steel piles. The ground floor has a cross-shaped lobby that was originally ringed by commercial spaces.
The Insurance Company of North America bought the site in June 1931 for $2.5 million. The A. L. Hartridge Company began construction in April 1932, and opening day was May 2, 1933. The upper stories held offices, which were later converted to residences in 1999 by Rockrose Development, a company that bought the building in 1996. It is listed in the National Register of Historic Places.

- One piece with the ground
- 99 John Street 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.

- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
