About this 3D model

This is a small-scaled model of Chicago Trump Tower. I think I got most of it down. The top of the tower is a little inaccurate, but it will still print just fine. I will upload a picture later. Mine came out perfectly. I originally took a SketchUp model and tried running that, but it did not print out successfully at all. I had to re-model the whole tower from scratch for the most part. It's about as accurate as I could get it. If there are any errors, please let me know. *This was a test to make sure my students would be able to print out a small-scaled model of their Chicago Architectural research project.
