About Cologne Cathedral
Cologne Cathedral, called the Kölner Dom in German, is a Catholic cathedral in the city of Cologne (North Rhine-Westphalia, Germany) and the seat of its archbishop. It is a renowned monument of Gothic architecture, and it became a World Heritage Site in 1996. Standing 157 m (515 ft) tall, it is the tallest cathedral in the world and the world's tallest twin-spired church. Only two churches in Europe are taller, Sagrada Família and Ulm Minster. Within Cologne itself, only the telecommunications tower rises higher.
Archbishop Konrad von Hochstaden laid the foundation stone on August 15, 1248. The medieval builders intended a large building to hold the reliquary of the Three Kings. Construction stopped in the years around 1560. For 400 years, a huge crane atop the south tower, which stood complete to its belfry level, remained a landmark of the Cologne skyline. Attempts to complete the building began around 1814, although proper funding did not arrive until the 1840s.
Civic effort drove the completion. The Central-Dombauverein, founded in 1842, covered two-thirds of the costs, and the Prussian state covered the remaining third. Work resumed in 1842 from the surviving medieval plans and drawings, with more modern techniques such as iron roof girders, under Ernst Friedrich Zwirner until his death in 1861. In 1880 the cathedral was finished, following the original medieval plan, and its two huge spires give it the largest façade among the world's churches.
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 | 43 mm | 1:3,750 |
| 200 mm | 54 mm | 1:3,000 |
| 256 mm | 69 mm | 1:2,344 |

- Open lattice twin spires
- Both tall spires are open lattice. Print friendly adapts them to the print scale; Full detail keeps every bar on a larger print, ideally with 0.12–0.16 mm layers.
- Slim pinnacles along the roofline
- Slender pinnacles line the sides and a thin spire rises from the middle of the roof. Print slowly with good cooling, and a bigger print size keeps them crisp.
- One piece with the ground
- Cologne Cathedral 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. Cologne Cathedral 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.
