About Reunion Tower

Reunion Tower is an observation tower in downtown Dallas. Its address is 300 Reunion Boulevard, within the Reunion district. It rises 171 m (561 ft) and is known as one of the most recognizable landmarks in Dallas. The district is named after La Reunion, a commune of the mid-nineteenth century. Welton Becket & Associates designed the tower, and Henry C Beck Company was the prime construction contractor. Locals also call it "The Ball".

Four shafts of concrete poured in place support three floors with circular plans. The central shaft is cylindrical and holds the stairs and mechanical equipment, while three rectangular shafts with elevators rise in parallel beside it. Glass panels form the outer wall of each shaft, giving views across the city on the 60-second ride up. The top three floors sit inside an open-air sphere, a geodesic dome of aluminum struts, and aluminum circles with a light at their center cover each of the 259 points where struts meet.

Construction finished on February 2, 1978, alongside the Hyatt Regency Dallas at Reunion. The tower and hotel belonged to an urban redevelopment project, one that renovated historic Union Station too. The public could visit from the official opening on April 15, 1978. Marketing consultants first proposed the name "Esplanade", but Woodbine Development Corporation's John Scovell, the developer, rejected it in favor of Reunion, after he looked into the La Reunion colony.

Tall shaft, slow printing
The shaft is long and thin compared with its height. Print slowly with good cooling so it stays straight, and choose a larger print size for a sturdier shaft.
Open lattice sphere on top
The sphere is an open lattice of fine struts. Print friendly adapts it to the print scale, and Full detail keeps every strut on a larger print with 0.12–0.16 mm layers.
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. Reunion Tower 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.

Common questions

Is there a Reunion Tower 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. Reunion Tower grows with the print: about 47 mm tall on the default 160 mm print. For a model larger than your printer bed, Project Mode splits the area into tiles.
