Concrete Culverts as typically found near roads or railways to allow water, people, or farm animals to pass through without affecting the railway or road. To create a tunnel under the railway you will need to print an entrance section for both sides and may need to print multiple box sections to cover the width of the railway or road.

If you like these but require something a little different then please approach me via this site to do a project for you.

There are two versions included, both come with straight or angled entrances. See photos for more information. The box section culverts are based on internal dimensions, the following dimensions are real-life measurements and not the models. The two standard dimensions used are 2.5m x 2m and 2.5m x 1m, and wall thickness is 0.25m.I have test-printed these on an Anycubic Photon Resin Printer

This has been modeled at OO Gauge, 1/76 scale, if you need them a little bigger or smaller then just change the scale when printing.for HO Gauge print at 87%, 1/87 scale,for O Gauge UK print at 175%, 1/43.5 scale,for O Gauge International print at 158%, 1/48 scale.for N Gauge UK print at 51.5%, 1/148 Scale. (Caution: I have not test printed this in this scale).

All items can be easily printed on resin and filament printers, print size is dependant on print area.As normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the design of the model too much.

I use AnyCubic Water Washable Resin for most of my items but use AnyCubic ABS Like Resin for anything that needs to be stronger and tougher.
