This is a 3D model of a track sleeper grid for scale models of H0 railways. You can print it on a 3D printer if you are not satisfied with the finished products for some reason. The length of 188 mm was chosen so that the most common 3D printers could print it. These sleepers are suitable for rails with a base width of 2.2 mm and a head width of 1.2 mm, then the track width will be 16.5 mm. You can simply glue the rails or melt the “crutches” with a soldering iron, pressing the soles of the rails to the base. You can print the sleepers directly with the rails if you don't need electricity to power your model.
