High-detail 3D-printable model of a heavy semi truck tractor with a conventional cab, designed for dioramas, model railway layouts and display scenes. The model represents a real-world tractor unit with fifth wheel and exposed chassis detail for easy kitbashing and customization. Files are supplied untextured and ready for printing — ideal for painting, weathering, or converting into yard/roadside scenes. Print orientation and small supports are recommended for the axle and underframe detail; scale to match your layout (commonly used with HO/1:87).
