About this item
- 【JMBricklayer 3-in-1 Mini Engine Model Set 60023】Build three complete engines from one set — a V6, an Inline-4 (L4), and a Boxer-4 (B4). Each engine is assembled separately, allowing you to explore and compare different cylinder layouts and mechanical structures while experiencing the unique engineering character of each configuration.
- 【Compare Three Classic Engine Layouts】Discover how different engines work by building three distinct configurations: the compact Inline-4, the smooth V6, and the low-center-of-gravity Boxer-4. Each layout demonstrates unique mechanical characteristics, making the building process both educational and deeply engaging.
- 【Manual Crank – See the Motion】No motor needed. This model uses a hand-crank mechanism to activate the pistons and crankshaft. Turn the crank and watch the synchronized piston movement in action — a clear, hands-on way to understand how internal engine parts work together.
- 【Beginner-Friendly & Rewarding Build】With 711 precision pieces, this set offers a satisfying yet accessible challenge for teens and adults. The step-by-step assembly process helps builders learn basic engine structures while enjoying a hands-on project that rewards patience and focus.
- 【Compact Size for Display & Learning】Each finished engine measures about 4 × 4 × 3 inches (10 × 10 × 7.6 cm) — perfect for desks, bookshelves, classrooms, or workbenches. These mini engine models combine mechanical curiosity with a clean, display-friendly design, offering everyday inspiration for car lovers and STEM learners.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
