The file 'N-Scale Concrete And Steel Truss Bridge – For Two Tracks 3D Printer Model' is (stl,f3z) file type, size is 2.5MB.
Loved Jeff's original, decided I needed room for two tracks - and curves, so re-modeled from scratch based on Jeff's basic design.
Fusion file allows end of curved span to be dragged to change length and shape of curve.
