About the Spodek
Spodek, a multipurpose arena complex, stands in Katowice, Poland, and opened on May 9, 1971. Besides the main dome, it has an ice rink, a gym, a hotel and three large parking lots. It was Poland's largest indoor venue of its type until Tauron Arena surpassed it in 2014. The hall can hold around 11,500 people, though the practical limit is 10,000, or even 8,000, when stage set-ups block the view.
The Polish word spodek means saucer, and the building's shape also calls to mind a flying saucer, resembling a UFO. Posters promoting redevelopment in Katowice have used it as an unofficial logo of the city. Music concerts are an especially common kind of non-sport event, and ice hockey clubs call it home in the winter months.
The idea of a large venue dates to 1955, and a contest picked the design. The site was a mining waste dump near the city center. Rumors of design flaws spread, including that the dome would collapse once the scaffolding came off, and in 1964 work stopped for 18 months. The architects and chief engineers were inside the dome when the supports were removed, and 3,500 soldiers marched through the hall as an endurance test before it opened. Maciej Gintowt and Maciej Krasiński used the principle of tensegrity, with Wacław Zalewski as structural engineer.
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 | 10 mm | 1:3,750 |
| 200 mm | 12 mm | 1:3,000 |
| 256 mm | 16 mm | 1:2,344 |

- Wide saucer roof
- The wide roof overhangs the ring of walls and entrances below it. Print friendly adapts thin edges like this to your print scale; Full detail keeps them, best on a larger print.
- Fine ribs and small stairs
- The roof has fine radial ribs, and the base has small stair and entrance details. Layers of 0.12 to 0.16 mm keep this detail crisp.
- One piece with the ground
- The Spodek 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 Spodek 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 Spodek 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 Spodek 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 Spodek grows with the print: about 10 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.
