N-Scale 120mm long iron bridge

This N-scale iron bridge is designed to span a gap of 11cm. The bridge is 12cm long and is printed without supports , in grey PLA. The bridge is 2.4cm wide - so most trains will fit. All my trains fit perfectly.
It is printed on my Flashforge Finder which has a bed of 14 X 14cm - Even at lo-res the print is acceptable. The iron girders are clearly visible. (see photo attached)

Extra file ADDED (for a 28mm wide bridge - which seems big enough to handle most other trains. )if 24mm is too narr
