About the Alamodome
The Alamodome is a domed indoor multi-purpose stadium at the southeastern edge of downtown San Antonio, Texas. It opened on May 15, 1993, after costing $186 million to build. The city wanted it to draw more conventions and to lure a professional football team, and it also placated the Spurs' demand for a bigger arena. The rectilinear five-level facility seats up to 64,000 people for a typical football game or marching band competition, with expansion possible to 72,000.
The stadium was designed to convert easily into a basketball or hockey arena, a switch that takes 12–18 hours for the retractable seating and the playing surface. In arena form it seats 20,662 and can reach 39,500 with the upper level open. A smaller auditorium setup, branded the Illusions Theater, seats upwards of 11,000. Two permanent ice rinks of Olympic size are also built in, usable for figure skating, speed skating and NHL games.
The San Antonio Spurs called the Alamodome home between 1993 and 2002, and their first NBA championship season, against the New York Knicks, came in 1999. It hosted the 1996 NBA All-Star Game. Spurs management and fans later came to dislike the dome's poor sight lines and cavernous feel, and the team moved to a new arena after the 2001–02 season. The annual Alamo Bowl takes place there, and the UTSA Roadrunners football team started using the stadium in 2011.

- Corner masts and thin cables
- Four tall masts with thin diagonal cables rise at the corners. Print friendly adapts thin parts like these to your print scale; Full detail keeps them, best printed slowly with good cooling and 0.12 to 0.16 mm layers.
- Seating rows and roof details
- The stands show many fine tiers, and the roof carries a patch of small studs. A larger print keeps these details easier to read.
- One piece with the ground
- The Alamodome 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 Alamodome 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

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 an Alamodome 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 Alamodome grows with the print: about 26 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?
