N Scale Small Gas Station Building
This is a model of a small gas station building. It can serve as some other business building. It has a roughly 10’ by 20’ footprint. If you wish to add roof overhangs you can put paper or thin card on the roof.
I print my models on a filament (FDM) printer. That's what they're designed to be printed on. I printed this structure at 50% infill. Print the structure floor-side down and no supports will be needed.
