W12 Engine Model Kit, 1400+PCS Motorized Visible Simulation 3D Wooden Engine, DIY Mechanical Engineering STEM Educational Display Collection Model

Features: 

.Authentic W12 Mechanical Architecture: Modeled on the real W12 engine layout, including cylinder block arrangement, timing chain system, camshafts, pistons, and valves; wire-cut gears and linkage structures reproduce real mechanical motion logic, allowing completed assembly to simulate visible engine operation.
.Full Wooden Transmission System: Precision-cut wooden gears and connecting rods create synchronized crankshaft-to-piston movement, accurately reflecting real engine kinematics while delivering both visual impact and mechanical insight.
.High-Precision Laser-Cut Components: Every component, from hollowed cylinder patterns to gear tooth profiles, is laser-engraved for consistent accuracy; over 1400 interlocking parts achieve tight tolerances, supporting smooth motor-driven motion without jamming.
.Deep Immersive Assembly Experience: The 1400+ piece structure requires approximately 20–30 hours of assembly, encouraging sustained concentration, spatial reasoning, and hands-on problem solving, with a strong sense of completion once the dynamic system is operational.
.Mechanical Demonstration and Long-Term Display Value: The motorized dynamic operation visually demonstrates crank–connecting rod mechanisms and valve timing principles, making the finished model suitable for mechanical study, structured display, and long-term collection.
