Chicago's Willis Tower with dual colors so that the antenna stick out well. I had to make the antenna a little larger than I wanted so that it would print. Other than that, everything else is to scale. I will have the single extruder design on here as well.


4.8 inches tall with the antenna, 4 inches to the top of the building. I'm still struggling with getting the first couple levels of the second color to come out well but I'm not making it easy with such a thin object to build. It may be more reliable with support added for the antenna.

There will be more Chicago buildings to come, I'm going to try to keep them to scale relative to each other as much as possible.

You have to at least mention the fact that most Chicagoans still call this the Sears Tower.  Thanks for posting, I'll be printing this tomorrow.  

Haha, this is true, I'll fix it. I'm a new transplant so I am from the Willis age. I am going to start making a bunch of the buildings here, I also plan on turning these into shot glasses at some point but won't do them to scale
