This is a collection of railroad crossings for the marklin C-track miniature railroad system. Now you can print your own railroad crossings and cover them with plaster on any other material to make a genuine-looking crossing without the plastic-look.I found out that the best result is achieved when printing the ramps on their side. And you can fit a lot of them on the bed in a single print. That is why I already put them on their side in the design. Sizes are 7mm high (1 mm lower than the plastic rail bed), 40 mm wide and 75 mm long.When printing on the side make sure the bed temperature is correct, otherwise the thin ends will curl up. This is not a problem when used becase this will be covered with plaster.Edit 22-12-2012: Added ramps 80 mm wide for 2 lane roads (AA, BB etc.)
