High-detail 3D-printable miniature of the 1987 Buick Regal Grand National coupe. This digital model is optimized for clean prints and hobby use — perfect for dioramas, model-railroading, display pieces, and collectors. Features accurate exterior proportions and crisp surface detail suitable for common scales (examples: 1:18, 1:24, 1:43, 1:64, HO 1:87, N 1:160). Files are supplied as ready-to-slice STL meshes; recommended printing settings: 0.1–0.2 mm layer height, moderate infill (10–20%), and supports for overhangs. Post-processing and painting will produce the most realistic results. No physical item included — this listing is for the downloadable 3D model only.
