I need a print-ready 3-D model of my customer’s steel building that will serve as a keepsake gift. The finished piece should sit comfortably in the 6–12 inch range, so please size the file with that scale in mind. The brief calls for moderate detail—key architectural features must read well when printed, but we can avoid ultra-fine texturing that won’t show at this size. What absolutely has to be there are the roof details as well as the structural elements: steel columns, steel beams, and the roof and wall panels. I’d like each of those parts modeled as separate shells so I can print them individually and glue everything together afterward. To finish the presentation, include a few cows proportioned to match the building’s scale; they’ll help convey size when the gift is on display. Preferred deliverable • Clean, watertight STL (or OBJ) files for every separate component, tested in a slicer such as Cura or PrusaSlicer and ready for FDM printing. If you build in Blender, Fusion 360, SolidWorks, or a similar CAD environment, that’s perfect—just export to STL and share the native file in case we need a tweak later. Accuracy, printability, and proper part separation are the benchmarks I’ll use to accept the work.
