3D Printed Bridge

This is a 3D printed bridge that can support over 100 times its own weight. The members in the still file section above this description are printed as follows: Members 1 and 3=100% infill, members 2 and 4=30% infill. The load to weight ratio of this bridge is a whopping 137! The members can be slightly fragile at the points of connections, and for this reason the individual stl filedps for each member are included for piece by piece printing.
