A Must-Have for Mechanics Enthusiasts!

BLDB has introduced the stunning 1/10 scale OHV inline 4-cylinder diesel engine metal assembly kit. This innovative product caters to adults and teenagers alike, supporting the growing trend of STEM education and the importance of screen-free time.

The 3D metal puzzle contains over 300 meticulously crafted pieces, designed to provide a genuine and enjoyable assembly experience. This kit is not just a toy; it is an intricate decorative collectible for your office or study, showcasing the beauty and complexity of mechanical engineering.

Why Choose the DM115 Model?

1. Historical Design

In an era where DOHC (Dual Overhead Cam) engines dominate the market, this kit emphasizes the classic OHV (Overhead Valve) design, a pivotal moment in the history of internal combustion engines. This engine’s structure allows you to observe the entire mechanism, including camshafts, pushrods, and rocker arms. Watching the fundamental principles of intake, compression, combustion, and exhaust in action provides a profound understanding of engine mechanics, making it a unique educational tool.

2. High-Quality Materials

Crafted from high-strength stainless steel and aerospace-grade aluminum alloy, this kit is distinguished from standard cheap metal puzzles. The aluminum parts undergo a luxurious anodizing treatment, creating a durable surface that resists fingerprints, rust, and discoloration—even after years of use. This ensures your model maintains its stunning appearance.

3. Dynamic Experience

Using a built-in motor drive system, this kit provides continuous operation for over sixty minutes, allowing admirers to appreciate the synchronized movements of pistons and gears in real-time. With a USB power supply, you can create a peaceful atmosphere at your desk, complete with the soothing sounds of mechanical movement, turning assembly into a mindful activity.

4. No Glue Required

Engineered with over 300 parts, the DM115 utilizes a screw-based assembly method, requiring no adhesives. This precision engineering demands high tolerance levels during manufacturing, ensuring an accurate fit for every component. The experience of tightening metal together mimics real engine assembly, allowing for adjustments if needed, fostering logical thinking and concentration.
