About the Casa Grande Ruins
Casa Grande Ruins National Monument preserves a group of Hohokam structures from the Classic Period (1150–1450 CE) in Coolidge, Arizona. The site holds the ruins of several buildings inside a compound wall. In the early 13th century the Hohokam were farming the Gila Valley, and archeologists have found evidence that the ancient people of the Sonoran Desert who built it practiced irrigation farming on a wide scale and kept up extensive trade ties lasting more than a thousand years, up to about 1450 CE.
The name Casa Grande means big house in Spanish and refers to the biggest structure at the site, what remains of a four-story building possibly abandoned by 1450. It is made of caliche and has survived the extreme weather for about seven centuries. Outer rooms three stories high surround an inner structure four stories high. The builders used traditional adobe methods, forming the walls from damp adobe, letting it dry, then building it up with more, and horizontal cracks on the thick outer walls mark where one course ends and the next begins.
Father Eusebio Kino, the first European to see the complex, named it Casa Grande in November 1694. On June 22, 1892, President Benjamin Harrison proclaimed the 480 acres around the ruins Casa Grande Reservation, the country's first prehistoric and cultural reserve. President Woodrow Wilson re-designated it a national monument on August 3, 1918. Frederick Law Olmsted Jr., a Boston architect, built a ramada in 1932 to shelter the ruins, and visitors may observe only from outside.
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 | 6 mm | 1:3,750 |
| 200 mm | 7 mm | 1:3,000 |

- Wide roof on slender posts
- A wide hipped roof stands on four slender posts above the ruin. Print slowly with good cooling, and use Print friendly to adapt the posts and the thin roof edge to the print scale.
- Finial and wall courses
- A thin finial rises from the roof ridge, and the walls below show fine horizontal courses. Layers of 0.12–0.16 mm keep the courses crisp, and a larger print size protects the finial.
- One piece with the ground
- The Casa Grande Ruins 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 Casa Grande Ruins 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 Casa Grande Ruins 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 Casa Grande Ruins 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 Casa Grande Ruins grows with the print: about 6 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.
