About the Washington Monument
In Washington, D.C., the Washington Monument is an obelisk standing on the National Mall. It honors George Washington, a Founding Father and first U.S. president. The monument rises 169 m (555 ft), and to its west lie the Lincoln Memorial and the Reflecting Pool. Bluestone gneiss forms its foundation and granite its main structure, while the outer facing uses three different kinds of white marble, a result of repeated interruptions during construction.
Work began in 1848 and stopped between 1854 and 1877 because of money problems, the Civil War and a fight for control of the Washington National Monument Society. The stone structure was finished in 1884. Dedication came on February 21, 1885, and public access began on October 9, 1888. Robert Mills of South Carolina created the original design, but his planned colonnade was left out for lack of funds, so a bare obelisk was built. Between 1884 and 1889 it was the tallest structure in the world, until the Eiffel Tower overtook it.
The monument is hollow inside and, outside, a stone obelisk in the Egyptian style: a column 152.4 m (500 ft) high topped by a pyramidion 16.8 m (55 ft) high. Its walls taper as they rise and rest on six arches. Iron stairs spiral up the inside walls around a central elevator. The pyramidion holds eight windows for observation, plus eight red lights that warn aircraft, and its marble capstone ends in a small aluminum pyramid. A circle of poles around the monument carries fifty U.S. flags, one for each state.
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 | 45 mm | 1:3,750 |
| 200 mm | 57 mm | 1:3,000 |
| 256 mm | 72 mm | 1:2,344 |

- A tall, slender shaft
- The obelisk is a narrow tapering shaft with a pointed top. Printing slowly and letting layers cool helps the tall thin form, and layers of 0.12 to 0.16 mm keep the tip crisp.
- Fine horizontal lines
- Faint horizontal lines run up the shaft. Thin layers help them show, and a larger print keeps them readable.
- One piece with the ground
- The Washington Monument 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 Washington Monument 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 Washington Monument 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 Washington Monument 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 Washington Monument grows with the print: about 45 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.
