High-detail 3D-printable model of the 2019 Freightliner Cascadia tractor designed for dioramas, model-railroading, and scale displays. The model is provided as printable sub-assemblies (cab, chassis, wheels, mirrors, and accessories) to fit desktop printers and simplify painting and finishing. Files included: STL and OBJ. Recommended print settings: 0.2 mm layer height, 0.4 mm nozzle; supports required for mirrors, undercarriage details, and any overhangs. Compatible with common hobby scales (1:18, 1:24, 1:48/O, 1:64/S, 1:87/HO, 1:160/N). Post-processing: sanding, priming, and painting will bring out the fine surface detail.
