These are some fittings to make a victorian pier for 009 or GN15 model railways. You can make either single spans, or use the double tops or triple tops to make different types of connections. I'll post some more examples as I print more. Its up to you to work out the decking, I am constructing a 009 pier at present with coffee stirrers.
To keep the price down, 9mm wooden doweling is used for the uprights, although I have been using plastruct girder extrusion for the cross beams. I have also a lower girder STL as well in case you dont want to get the plastruct. Works out cheaper
