NS Elo227 Dutch railways

This is a my first try at a HO scale train wagon. The model represents a Dutch railways (NS) scrap metal wagon with designation Elo227. The wheels used for this model are 11.3mm diameter and the short couplers are made by Roco. The model runs very smoothly trough switches, but for the purpose of combining it into a longer train, some (scrap) weight should be added. The model prints to reasonable detail on an Ultimaker. Commercial 3d printing would result in an even finer model.
