Approximate dimensions in the displayed assembled configuration:

161.75 × 44.40 × 105.24 mm — Length × Width × Height

The final dimensions vary depending on the boom extension, lifting angle, hook position, and outrigger configuration.

For stronger pins, clearer details, and easier FDM assembly, printing at 150–200% scale is recommended.

Included Formats15 separate STL files for 3D printingSTEP CAD files for editing, scaling, and customization

Print the components separately and test-fit the pins, boom sections, and moving joints before final assembly. Minor sanding or hole adjustment may be required depending on printer calibration and material.

Suitable for construction vehicle collections, mechanical models, engineering displays, dioramas, educational projects, and 3D printing enthusiasts.
