About Kalmar Castle
Kalmar Castle (Kalmar slott in Swedish) is found in the city of Kalmar, in Sweden's Småland province. Its history begins in the 12th century, when a defensive tower rose on the site around 1180. The castle's strategic position, close to the former Danish border, led to its historical name "the Key to the Kingdom" (Rikets nyckel in Swedish). In 1397 it was where the Kalmar Union came into being, placing Denmark, Norway and Sweden (Finland then belonged to Sweden) under one monarch, Queen Margaret I of Denmark.
Around the end of the 13th century, King Magnus Ladulås ordered a new fortress around the original tower, complete with a curtain wall, rounded corner towers and a pair of square gatehouses. In the 16th century the Vasa kings rebuilt the medieval fortress as a Renaissance palace. Under King Johan III, the architect Domenicus Pahr began the renovation in 1574. Except for three, the towers were given a uniform height and lead roofs, the windows were made square, and the king had the facade painted white and the roof red.
The Siege of Kalmar, the chief battle of the Kalmar War (1611–13), badly damaged the castle, and a fire in 1642 did further harm. From the late seventeenth century it was left to decay. Restoration started in 1856, and by 1891 the castle had taken on the silhouette it keeps. From 1919, Martin Olsson oversaw work on the earthworks, moat, bridge and drawbridge, and in 1941 water once more ringed the castle. Statens fastighetsverk describes it as the Nordic region's best-preserved Renaissance castle.

- Needle-tipped round towers
- The round corner towers end in slim spires. Print slowly with good cooling, and use Print friendly to adapt the tips to the print scale or Full detail on a larger print.
- Tiny stepped gables
- The stepped gables and small roof windows are tiny details. Layers of 0.12–0.16 mm keep the steps crisp, and a bigger print size gives them more room.
- One piece with the ground
- Kalmar Castle 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. Kalmar Castle 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.
