This is a german hopper car from the national german railway company DB. You can print the car body without supports. The overhangs are smooth enough to print it without support. It was no problem on my ender 2 V2. While printing, the platforms should lay on the railings. Part1 and Part2 should be used to mount the Bogies to the Body. I used All - purpose - adhesive to stick the parts together. You can equib the designed bogies with 36" wheelset of every common manufaturer.
