About the Calgary Tower
In downtown Calgary, Alberta, Canada, the Calgary Tower rises 190.8 meters (626 ft) as a free-standing observation tower. Marathon Realty and Husky Oil proposed it jointly, as one element of an urban renewal plan and a way to mark Canada's centennial of 1967. Its first name was the Husky Tower; it became the "Calgary Tower" in 1971.
Work started on February 19, 1967, and took 15 months. Builders formed the column with an unprecedented continual concrete pour, starting May 15, 1967 and finishing 24 days later. The public opening came on June 30, 1968. At that point the tower was Calgary's tallest structure, and Canada's tallest outside Toronto.
A. Dale and Associates designed the structure to resist earthquakes and winds reaching 160 km/h (100 mph). The weight comes to about 10,884 tonnes, with 60% of it below ground. Building it cost a total of $3.5 million. The tower belongs to the World Federation of Great Towers as a founding member.

- Slender shaft and thin mast
- The long, thin shaft and the antenna above the observation pod are the delicate parts. Print slowly with good cooling, and use Full detail only at larger sizes where the mast stays thick enough.
- One piece with the ground
- The Calgary Tower 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 Calgary 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.
