Highly detailed 3D-printable miniature of the KATO NK 200S II 20-ton truck crane, optimized for hobbyists and diorama builders. This digital download includes separate STL files for the chassis, superstructure, boom and outriggers to simplify printing and assembly. The model preserves authentic proportions and surface detail for realistic results on model-railroad layouts and construction dioramas. Recommended for HO (1:87), N (1:160), and S (1:64) model-railroad scales but easily rescaled for other sizes. For best detail, print at 0.08–0.16 mm layer height; parts are split to reduce required supports and to allow printing in common build volumes. Assembly, gluing and basic finishing required. This listing is for a digital 3D model (STL files) only — no physical item will be shipped.
