Z scale center cupola caboose

This is a model of a center-cupola caboose. 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 roof and floor should be printed at 100% infill. I print the body at 75% infill for weight. Print all the pieces flat-side down and no supports will be needed.
