This 1:87 (HO) master STL reproduces a 1930s wooden tabletop radio cabinet with the defining external features: a recessed circular metal dial bezel, four round bakelite-style control knobs in a two-over-two layout, a carved multi-arched front grille with a speaker cloth backing plane, vertical fluted corner pillars, and a low plinth base. The download includes a single 1:87 master STL and a concise readme with conversion factors and printing guidance. Geometry is exported as clean CAD solids and grouped into cabinet shell, decorative grille, speaker cloth plane, dial bezel, knobs and fasteners — ideal for painting, weathering, and drop-in use on HO model railroad interiors, diorama scenes, or display cases. The mesh intentionally omits readable branding text while preserving historical attribution (Atwater-Kent) in the listing. Printing tips: resin printing recommended for crisp grille work; FDM printing works well with light supports in the grille area and 0.2 mm layer height. Use the included conversion table if you need a different scale — only the 1:87 master STL is provided.

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