Here is my depiction of a Fotomat / Guard Shack. Access holes include for lighting. Sand to exact fit.
Building: To get the most detail print with your lower layer height, slower speed down and 100% fill for detail ( N scale mainly ) Most Importantly at 45 degree orientation to get the most detail, no supports needed. For N Scale.
Windows: Again lower height, slower speed, 100% fill, 45 degree orientation. For N scale, scale design to 1.0. Once printed trim parts tree from windows, trim hinge points to get 90 degrees bends, glue in place on building.
Roofs: 3 Versions, Plain Roof, Fotomat Roof, Kodak Fotomat Roof, your pick, your purpose.
Again, lower height, slower speed, 100% fill, 45 degree orientation.
Sand to fit, glue with model glue.
