These parts can be printed with a standard 0.4 nozzle. Some wire is needed for the cabin brake handle en fixing the brake levers (Remstanghevel). The cover picture shows the position of the parts. Good luck with the assembly.
The author remixed this model.
These parts are an add-on to the model of Beusekomse baan the Nederlandse Spoorwegen 636 Shunting locomotive to detail the locomotive with suitable brakes.
