- 【JMBricklayer 3 in 1 Mini Engine Model Set 60023】Build three separate engine models in one set — a V6, Inline-4 (L4), and Boxer-4 (B4). Each engine is assembled individually, allowing builders to explore and compare different cylinder layouts and mechanical structures while experiencing the unique design of each configuration
- 【Compare Three Classic Engine Layouts】Discover how different engines are designed by building three distinct configurations. The compact L4, the balanced V6, and the low-center-of-gravity B4 boxer engine each demonstrate unique mechanical characteristics, making the building process both educational and engaging
- 【Manual Crank Mechanical Motion】This engine model features a hand-crank mechanism that activates pistons and the crankshaft without using a motor. By turning the crank manually, you can observe synchronized piston movement and better understand how internal engine components work together
- 【Beginner-Friendly Mechanical Build】With about 711 precision pieces, this building set offers a satisfying yet approachable challenge for teens and adults. The step-by-step assembly process helps builders learn basic engine structures while enjoying a rewarding hands-on building experience
- 【Compact Models for Display & Learning】Each finished engine measures approximately 4 × 4 × 3 inches, making them ideal for desks, bookshelves, classrooms, or workspaces. These mini engine models combine mechanical curiosity with a clean display design for everyday inspiration
