19 mm tall on a 160 mm print
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.
- A slim tower with a sharp spire
The tower narrows into a tall pointed roof with small turrets at its base. Layers of 0.12 to 0.16 mm and a slower print speed help the spire and turrets stay crisp.
- Small clock faces and windows
The tower walls carry little clock faces and narrow windows. A bigger print size shows them more clearly; Full detail keeps them all, while Print friendly adapts them to your scale.
- One piece with the ground
The Prague Astronomical Clock 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 Prague Astronomical Clock 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 the Prague Astronomical Clock
The Prague astronomical clock, also called the Prague Orloj, is a medieval timepiece fixed to Prague’s Old Town Hall. It is fixed to the hall’s southern wall, in the Old Town Square. An astronomical dial shows the positions of the Sun and Moon along with other astronomical details, and a calendar dial carries medallions for the months. Every hour the Apostle figures move in a show, and sculptures, notably a skeleton representing Death, strike the time. Statues of Catholic saints flank the clock.
The oldest part, the mechanical clock and astronomical dial, goes back to 1410. Horologist Mikuláš of Kadaň and Jan Šindel, a professor of mathematics and astronomy at Charles University, created it, and the earliest written record of the clock is dated October 9, 1410. The calendar dial was added presumably around 1490, when gothic sculptures also decorated the facade. It was once believed that clockmaster Jan Růže, also called Hanuš, built the Orloj in 1490, but that attribution is known to be a mistake. The Apostle figures came after a major repair carried out in 1787–1791.
In the Prague uprising, on May 7 and 8, 1945, the Orloj was heavily damaged after the Nazis opened fire on the square’s south-west side. Fire swept through the hall and neighboring buildings, burning the wooden sculptures and the calendar dial face by Josef Mánes. After lengthy work the machinery was repaired and Vojtěch Sucharda restored the wooden Apostles, and the Orloj ran again in 1948. Local legend holds that the city would suffer if the clock were neglected.
About this model
The Prague Astronomical Clock is one of more than 4,300 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.
