This is a 3D CAD model of a crankshaft, accurately designed to represent the real-world engine component used to convert reciprocating piston motion into rotational motion. The model showcases piston, piston connecting rod, piston connecting rod cap, pin, piston rings making it suitable for educational, mechanical, and visualization purposes.

The geometry is clean and well-structured for rendering, animation, finite element analysis (FEA), or 3D printing. Perfect for use in automotive engine design, mechanical assemblies, or as a reference model for students and engineers.
