Designed in OpenSCAD. Fully parametric, within certain parameters at least. This is a simple model bridge, printable in a single part, or in three parts for larger bridges.
Does not work for all parameters, ramps need improving. These improvements will probably never be carried out, as I have printed what I needed and unless I find the need to print more bridges, that is probably the end of the development!
