This is a bridge pier for a railroad bridge. The dimensions are taken from an actual pier built by the Southern Pacific Railroad for a crossing of Los Gatos Creek in the Santa Clara Valley, California. I found dimensions in a set of Southern Pacific technical drawings at the California State Railroad Museum in Sacramento.
I printed these on a Form One resin printer. The walls may be too thin for ABS / PLA printers; filling in the hollow interior should make it easier to print. I've included the SketchUp file used to generate the STL file. Note that hollow models can have problems on liquid resin printers because of pressure when the tank presses against the model after each layer. The pier has a small hole at the top of the hollow section to allow resin to escape.
