Highly detailed 3D-printable miniature of an antique steam tractor (traction engine). Sculpted with period-accurate proportions and surface detail to work well in dioramas and model-railroad layouts. The model is optimized for printability with separate parts for wheels and boiler to simplify supports and cleanup. Recommended for HO scale (1:87) and other common model scales; can be scaled up or down to suit your layout. Printing notes: print upright or on its side for best detail; use 0.1–0.2 mm layer height for fine detail. Wheels are provided as removable pieces to make post-processing easier. No complex assembly required — light sanding and glue recommended. Designed for FDM and resin printing. Files included are ready-to-slice STL exports.
