Detailed 3D-printable miniature of an oil pump jack, designed for dioramas, model rail layouts and tabletop wargames. The model prints cleanly with minimal supports; parts are optimized for FDM and resin printers. Use PLA or resin for best detail, scale and paint to match your scene. Includes a single-piece main model with separate optional base for easy placement. Printing tips: 0.1–0.2 mm layer height recommended, support the walking beam and counterweight areas if printing upright. Thin features are strengthened in the model, but consider 20–25% infill for extra durability if printing large. Ideal for HO, N, O and 28–32 mm scale scenes (scale the file to match your project).
