Z scale Frisco dining car

This is a model of a scale 80' dining car similar to those operated by the St. Louis-San Francisco (Frisco) Railroad. The trucks/couplers I suggest for this model are Micro-Trains #959 or 959-A (aluminum).

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

For weight and strength the roof should be printed at 100% infill. The body can be printed from 50% to 75% infill for weight. Print both pieces flat-side down and no supports will be needed.
