HO 1:87 Midcentury 1940s–1960s Background Prop — single‑story commercial silhouette sized for model railroading, dioramas, and display backdrops. Product highlights - One single master STL scaled for HO 1:87. Miniature Reality ships a single 1:87 master file; conversion guidance is included so you can print at other scales. - Designed as a neutral midcentury background building: low profile, broad roof plane, shallow facade depth, simplified blocky volumes and bilateral symmetry. No storefront signage or brand marks; ideal as unobtrusive lot filler or a midground vignette. Mesh notes and print guidance This model began as a legacy MeshRef export and was finalized for print reliability: fragile edges and roof overhangs were thickened, microscopic holes were closed, and surface noise was reduced. For resin printing use 0.05–0.08 mm layers and orient the long roof plane to minimize layer steps; for FDM use 0.12–0.20 mm layers with 15–25% infill and orient to reduce visible layer lines. Supports should be focused under pronounced overhangs and recessed ledges. After scaling, always check wall thicknesses. Use cases - HO model railroad midground/background scenery - Small diorama vignettes where era suggestion is needed without heavy detail work - Shelf or display backdrop to frame foreground collectibles Limitations and provenance Era attribution (1940s–1960s) is from source metadata; identity confidence is low (0.30). This file is a scenic background prop, not a dimensionally verified replica. For custom scaling, additional file formats, or a research pass to convert this into a brand‑accurate model, contact Miniature Reality. License Hobby/personal use per platform terms.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
