Highly detailed 3D-printable miniature of a 1996 Peterbilt 378 daycab tractor. Modeled for hobbyists and diorama builders, this file set is optimized for printing at common model scales (HO/1:87 shown) and larger. The design is split into print-friendly components to preserve fine detail and simplify painting and assembly. Recommended print settings: 0.08–0.20 mm layer height for best detail, 10–20% infill, and supports for overhangs. PLA or PETG are good material choices for ease of printing; resin printers will capture the finest details. Small parts and trim may require careful post-processing and painting. Use scale-aware slicing to achieve the intended size for your layout or display. Files included: ready-to-slice 3D model(s) suitable for hobby printing.
