This is a 3D model of the western span of the San Francisco Bay Bridge I designed in OpenSCAD to be 3D printed. All of the smaller features such as the cabling and cross-beam supports have been made so as to be substantial enough to be picked up when sliced for printing (My early efforts had the smaller details simply disappear when sliced).
