Belluna Dome in 3D
The landmark on its own, at its size on a 160 mm print. Print friendly thickens thin parts for a 0.4 mm nozzle; Full detail keeps every part.

23 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.
- Inclined V supports
The paired V-shaped roof supports are the thinnest elements. Print friendly adapts them at small sizes; Full detail or a larger print keeps the open perimeter legible.
- Domed roof and fascia
The shallow membrane center, deep eaves fascia and radial seams need clean layers. Use 0.12–0.16 mm and a larger print to keep the roof surface and seams crisp.
- One piece with the ground
Belluna Dome 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. Belluna Dome 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 Belluna Dome
Belluna Dome is a baseball stadium in Tokorozawa, Saitama, Japan, and hosts the Saitama Seibu Lions of professional baseball. It is also known as Seibu Dome. The field and stands are covered by a roof, as in other indoor ballparks, but there is no wall behind the stands. Natural air therefore enters the field, and home runs can leave the stadium, which is not possible in typical domed stadiums.
It was built in 1979 without a roof and named Seibu Lions Stadium, as the Lions' new home ground after the franchise relocated from Fukuoka to Tokorozawa that year. The stadium was open-air at first. Its roof went up in two stages, one after the 1997 season and one after the 1998 seasons. At the start of the 1998 season it was renamed Seibu Dome, even though the roof was not yet complete. The Lions had first planned a new stadium in Odaiba, but the need for approval from three other Tokyo-based teams, local fans' opposition and the cost of a new build led them to add a roof instead.
