About The O2 Arena
The O2 Arena is a multi-purpose indoor venue on the Greenwich Peninsula, at the middle of the O2 entertainment district, in the south east of London, England. Its present form dates from 2007, and locals call it simply The O2. In 2008 it was the world's busiest arena for music, and it sold more than 1.2 million tickets in 2007 although it was open on only 200 days each year. Its name comes from its main sponsor, the telecommunications company O2.
The arena sits inside what used to be the Millennium Dome, a big domed structure meant to host an exhibition marking the arrival of the third millennium. The dome is 365 meters (399 yards) across and 52 meters (57 yards) tall. After the Millennium Experience closed at the end of 2000, the dome was leased in December 2001 to be redeveloped as an entertainment complex that was to include an indoor arena. Building the arena took from 2003 until 2007.
Cranes could not be used inside the dome, so the arena's roof was built on the ground within it and then lifted, with the rest of the structure assembled around it. The arena building stands apart from the other buildings in The O2 and occupies 40% of the whole dome structure. Its seating can be rearranged, and the floor can become a concert venue, an ice rink, a basketball court, an exhibition space or a conference venue. Echo was a design concern, an issue shared by many older concert arenas.
How it prints
Make this print opens the generator on a 800 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 | 20 mm | 1:5,000 |
| 200 mm | 25 mm | 1:4,000 |
| 256 mm | 32 mm | 1:3,125 |

- Masts and radiating cables
- A ring of tall masts holds thin cables that fan out across the dome. 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.
- Fine seams across the roof
- The wide, shallow roof carries many fine radial lines. A larger print keeps them easier to read.
- One piece with the ground
- The O2 Arena 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 O2 Arena 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 O2 Arena 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 The O2 Arena 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 O2 Arena grows with the print: about 20 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.
