Highly detailed 3D-printable miniature of the Caterpillar 315 hydraulic excavator. Designed for dioramas, model railroading, and scale layouts, this model captures the proportions and tracked undercarriage of the real machine. Files are prepared for printing at common scales and can be resized to suit HO, N, O, S, and several vehicle scales. Suitable for resin and FDM printing; some parts may require supports or can be printed in sub-assemblies for cleaner results. Ideal for construction scenes, industrial dioramas, and collectors of modern heavy equipment models.
