This bridge can be printed yourself with the included STL files. I have included all the components required to replicate this bridge except for the metal shafts that measure 2.75 inches and have a 3 millimeter diameter. This bridge has a load to weight ratio of 2130.4 grams (and perfect if your in the Intro to Engineering and Design class). Something that surprised my group was the impressive load to weight ratio.
