    Steam Age Meets The Age Of The Dinosaurs

    JMBricklayer Steampunk Marble Run 70003 is a building brick GBC (Great Ball Contraption) set that combines elements of the industrial steam age and the dinosaurs' age, providing a visually stunning effect. Powered by a dual-motor system, the JMBricklayer Steampunk Marble Run 70003 boasts the richest details, and most unique scenery, and features a diverse range of tracks. It's ingeniously designed as a cyclic closed-loop, powered by motorized operation, which drives the rotation of gears within the mechanism, thus propelling the entire apparatus. Assembling it requires a great deal of patience, hands-on skills, and critical thinking.


    JMBricklayer is a brand that specializes in selling Lego-compatible building block sets for ages 14 and up. Whether you are a novice, an enthusiast, a seasoned player, a reviewer, or a MOC designer, our doors are open for you! 


    What does it mean to back a project (pledge)?

    When you back a project, you’re pre-ordering the product. That means you'll get it once it's produced. Besides getting the product itself, you're also joining a community. Follow along the production process, take part in important surveys and give the creator valuable feedback.

    What is Kickstarter?

    Kickstarter is a launchpad for creators to raise funds for the initial production of their invention. Backers (that's you!) can support the creator by pre-ordering the product at a discounted price.
