The file 'N Scale House 209 3D Printer Model' is (stl) file type, size is 112.6KB.
I printed this with PLA and no support. I scaled up the original to get to N scale. Next, I pushed the windows and doors into the walls and resized some of them. Finally, I printed the roof separate from the empty building and then glued the roof on top.
