A compact double-sheave lifting pulley block with swivel top hook and lower eye, sized for / use. The piece presents clear industrial detail — rounded side plates, visible fastener bosses, and distinct sheave grooves — making it ideal for dioramas, model-railway layouts and display scenes. This listing includes one master file; scale conversion guidance is provided so you can resize the master to other scales in your slicer. For best printing results, orient the hook vertically and verify hole clearance if you plan to pass thread or chain through the eye. The block is modeled as a static prop focused on authentic surface detail rather than mechanical function. Great for freight house loading bays, engine sheds, shipyard scenes and workshop vignettes.
