High-detail 3D-printable miniature of the Kenworth W900 Aerodyne tractor. Optimized for hobby and diorama use, the model is supplied as separate printable parts (cab, sleeper, chassis, wheels, mirrors and accessories) to simplify printing and finishing. Files are provided as high-resolution STL, with parts split for easier supports and clean assembly. Recommended print settings: 0.12–0.2 mm layer height for FDM (0.05–0.06 mm for resin), 0.4 mm nozzle, moderate infill (10–20%), and supports for wheel wells and mirror mounts. Some light cleanup, sanding and glueing required; designed to accept aftermarket wheels and detail parts. Ideal for model railroading, tabletop dioramas, and scale vehicle collections. See included README for part list, suggested scale examples, print orientation, and basic assembly tips.
