This is a scale model of a type 3202A NMBS flat freight wagon.
These models were build between 1966 and 1967. This is the version with the break.
Couplings go in the NEM shaft that is included in the model. A slap of lead in the bottom (underside of the chassis) will keep the model better on the tracks. I use elastic tread to keep the couplings pointing straight. A string between the ‘pen’ components will do the trick.
The design uses the Marklin E700150 axels.
Designed for Prusa MK3s+ with 0.25 nozzle !
The author marked this model as their own original creation.
