This is a small bridge made to span a 5-inch gap for a school project. the truss proved to be very sturdy, holding a total of 30kg before failing catastrophically. Weighing in at only 18g (not counting the metal rods in the joints as they do not impact the strength of the actual truss) this truss can hold 1666.667 times its own weight. Attached files are: A picture of the bridge in the testing rig A picture of the bridge with the heaviest load born before breaking A picture of all members fresh off the printer a picture of the members being weighed An STL for each individual member An STL of all the members plated and ready to print (sized to a 200mm/120mm plane) A screenshot of the Member load Calculations according to MDSolids
