About the Walkup Skydome
Formally the J. Lawrence Walkup Skydome, this multipurpose indoor stadium stands on Northern Arizona University's campus in Flagstaff, Arizona. Its main tenants are the NAU Lumberjacks football team and the basketball teams for men and women, who compete in the Big Sky Conference.
It opened in 1977. For six years it was the largest clear-span timber dome in the world, a record that ended when the Tacoma Dome in Washington was completed in 1983. Wendell Rossman of Phoenix was the architect, Mardian Construction Company was the general contractor, and the wood used was southern yellow pine. The project cost $8 million, with more than half coming from voluntary student fee increases.
The dome is named for J. Lawrence Walkup (1914–2002), who led NAU as president from 1957 to 1979. Its street level sits at 2,095 m (6,880 feet) above sea level, which is higher than any other NCAA Division I FCS football stadium. Beyond sports, it hosts commencement ceremonies, concerts, conventions and trade shows.
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.

- Shallow dome, scalloped edge
- The low dome meets the ground in a ring of scalloped arches and slim supports. Print friendly strengthens those thin parts; a larger print or Full detail keeps the scalloped rim.
- Smooth curve
- A wide, gently curved roof can show visible layer steps. A layer height of 0.12–0.16 mm keeps the surface smooth.
- One piece with the ground
- The Walkup Skydome 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 Walkup Skydome 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 Walkup Skydome 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 Walkup Skydome 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 Walkup Skydome grows with the print: about 15 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.
