This is a rough approximation of Cincinnati's Roebling Suspension Bridge.
Print two roebling_3_120820c_truss.stl and four roebling_3_120821c_side.stl pieces.
First glue the sides to the truss parts with acetone or your favorite glue.
File one end of each bridge section perpendicular (square) to the bridge section.
Glue the filed ends together
