Z scale 40' steel gondola

This is a model of a 40' steel gondola. The trucks/couplers I suggest for this model are Micro-Trains #954 (Bettendorf Trucks).

I print my models on a filament (FDM) printer. That's what they're designed to be printed on.

For weight and strength the body and the floor should be printed at 100% infill. Print the body bottom-side up and the floor flat-side down and no supports will be needed.
