Here is my version of a Waffle House. I model N scale so to print scale to 25.4 NOTE REV1 files require no scaling. I included an interior, but for anything other than N scale it would lack detail you might need. My Interiors are designed to have a paper image attached the fixture for the details. 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 PRINT UPSIDE DOWN, no supports needed.
Base/Interior: Detail was designed for n scale so it is lacking if scaled above N. Because of this detail printing can be done at average height, average speed, average fill.
Roof: Average height, average speed, average fill
Windows/Doors: Lower height, slower speed, 100% fill for detail. Bend at joints, glue to building
Sign: average speed, average fill print 2, glue back to back
