About the Nelson Tower
Nelson Tower rises 46 stories and 560 feet (170 m) at 450 Seventh Avenue in Midtown Manhattan, on the block between 34th and 35th Streets. Finished in 1931, it was the tallest building in Manhattan's Garment District. H. Craig Severance designed it, and New York developer Julius Nelson originally planned and built it.
A rectangular base supports a body that steps back at different levels. Each section is brown stone with its top lined in white stone, and the crown is entirely white stone with a slight slope. One Penn Plaza, at 60 stories, sits across 34th Street and rises higher, but Nelson Tower can still be seen from most directions other than the southeast.
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.
| Print size | Landmark height | Scale |
|---|---|---|
| 160 mm default | 46 mm | 1:3,750 |
| 200 mm | 58 mm | 1:3,000 |
| 256 mm | 74 mm | 1:2,344 |

- Stepped setbacks
- The body steps back in several tiers, each with a ribbed edge. Print friendly adapts the small ledges to the print scale; Full detail keeps them, which suits a larger print.
- Slim, tall profile
- The upper tower is slim and tall, so print slowly with cooling and a layer height of 0.12 to 0.16 mm to keep the tiers crisp.
- One piece with the ground
- The Nelson Tower 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 Nelson Tower 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.
About this model
The Nelson Tower is one of more than 2,300 landmark models in Mini Skyline. They are made with AI, and each one is checked from four sides in its real surroundings before release. Everything around it is built from OpenStreetMap and Overture map data. If you would rather print the shape from map data, turn off Landmark models in the Buildings settings.
Common questions
Is there a Nelson Tower STL I can download?
Mini Skyline builds the file for you in your browser and exports 3MF, which every major slicer opens. If you need an STL, open the 3MF in your slicer and export it from there.
How big can I print it?
Any print size from 40 mm across. The Nelson Tower grows with the print: about 46 mm tall on the default 160 mm print. For a model larger than your printer bed, Project Mode splits the area into tiles.
Is it free?
Yes. Generation runs in your browser, with no account and nothing behind a paywall.
