This small footbridge is perfect for your n scale hikers to be able to safely cross a creek or small river on your model railroad layout or diorama.
The prototype for this bridge is located along a forest walk close to my home. It crosses our local creek. It's a pre-fabricated bridge which was brought on site and installed.
This has a lot of fine detail so if printing with an FDM printer, use a small nozzle such as a 0.20 or 0.25. Also slow down your printer and ensure that you use a brim and hot enough bed temperature to allow the print to stick.
The STLs are already oriented as they should be printed. No supports should be needed.
The floor grating could also be cut out of some very fine mesh or you could substitute a solid floor. While I modelled the square cutouts the original bridge has, my printer didn't do a good job of printing it out.
This model could also be printed on a resin printer - you may need to add supports for the horizontal rods on the bridge sides.
Once printed, glue the grating into the recess in the bridge floor frame - you may have to trim the grating to fit. Then glue the two sides to the bridge frame, with the horizontal rods facing out and the chamfered ends up.
