About the Comcast Center
The Comcast Center, also called the Comcast Tower, is a skyscraper in Philadelphia's Center City, with its address at 1701 John F. Kennedy Boulevard. The 58-story tower is 297 m tall. Robert A. M. Stern Architects designed it for Liberty Property Trust, and it is named after its lead tenant, the cable company Comcast. In the lobby, the Comcast Experience is a high-definition LED screen of 190 m2 (2,000 sq ft) that has become a tourist attraction. Shops and restaurants fill part of the building, and it links to nearby Suburban Station.
When plans were announced in 2001, the building was called One Pennsylvania Plaza, and it was redesigned twice before work started in 2005. The first plan was a 52-story tower of 230 m (750 ft) in kasota stone, like the Philadelphia Museum of Art, at an anticipated cost of US$400 million. One redesign swapped in a lighter granite and added a short pyramidal roof. The final redesign dropped the pyramid top and gave the tower a complete glass facade.
The lot, where 17th Street meets John F. Kennedy Boulevard, was occupied by a building that was home to the Defender Association of Philadelphia, plus a parking lot, and demolition ran from 2002 to 2003. The official groundbreaking ceremony took place at night on March 31, 2005, with a light show set to a piece of music called Elevation. The tower was designed to be environmentally friendly, and its waterless urinals were planned to save an extra 6,100 m3 (1.6 million US gallons) of water each year.
How it prints
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.
| Print size | Landmark height | Scale |
|---|---|---|
| 160 mm default | 80 mm | 1:3,750 |
| 200 mm | 100 mm | 1:3,000 |
| 256 mm | 128 mm | 1:2,344 |

- A tall, slightly tapering shaft
- The tower is a tall shaft that narrows a little toward a flat top. Printing slowly and using layers of 0.12 to 0.16 mm helps keep its straight edges clean.
- A fine panel grid
- The faces of the tower carry a fine grid of panel lines. Print friendly adapts them to the print scale; Full detail keeps more of them, which suits a larger print or a fine nozzle.
- 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 Comcast Center 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 this model
The Comcast Center is one of more than 2,300 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.
Common questions
Is there a Comcast Center 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. The Comcast Center grows with the print: about 80 mm tall on the default 160 mm print. For a model larger than your printer bed, Project Mode splits the area into tiles.
Is it free?
Yes. Generation runs in your browser, with no account and nothing behind a paywall.
