Customizable Speed Calibration Tower

I always struggle with trying to figure out what speed to print objects at, particularly when working with a new filament. This tower is designed to allow some systematic assessment of how fast a given printer can reliably extrude a given filament while maintaining printing accuracy. It includes smooth surfaces, embossed text, overhangs, and bridges that can all be inspected for variation in quality with speed.

Of course, many factors beyond just speed will affect print performance. In part
