As with the other famous Philly structures I've found to date on Thingiverse, this began life as a Sketchup Warehouse file. I live by the Art Museum and wanted a model of it I could print, so inspired by the work others had done on the Comcast Tower, Liberty Place and City Hall, I grabbed the Sketchup file. I then simplified that model, converted it to an STL and cleaned it up for printing. Enjoy!1) Print with support, flatten the base yourself or wait for me to do so. The model itself doesn't require support, just the underside of the hill it sits on. 2) Hum the Rocky theme while it's printing and imagine a tiny Rocky running the steps triumphantly.
