High-detail 3D-printable miniature of a 2009 Freightliner Columbia raised-roof sleeper tractor. Modelled with accurate cab proportions, roof fairing, and exterior details for realistic dioramas and model-railroad layouts. Supplied as ready-to-slice STL files optimized for both resin and FDM printing. Recommended print settings: 0.12–0.2 mm layer height for FDM, 50–100 µm for resin; 0.4 mm nozzle; 10–20% infill; add supports under mirrors, roof overhangs and belly if printing in a single piece. Model is split into printable sections (cab, chassis, optional wheels) to suit small-format printers — parts can be glued and seam-filled after printing. Ideal for HO (1:87), N (1:160) and S (1:64) scale layouts. Use appropriate primer and paint for best results. Licensed for personal and hobby use; see included files for details.
