Z Scale Bay Window Caboose
This is a model of a bay window 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 base pieces should be printed at 100% infill. I print the body at 75% infill for weight.
Print both the roof and base pieces flat-side down and no supports will be needed. Print the body with the bottom on the build plate and no supports will be needed.
