Ball Shooter Marble Run GBC




My redesign and rebuild of Akiyuki's Marble Run into a stand alone and reliable Great Ball Contraption. A high speed spinnig wheel shoots the ball up to the top after which then run down the marble run. With a thank you to dunes for creating the digital file with all those custom hoses and Jörg Schwarzländer (SWL) for the instructions! Parts list is without the ball container.

There are 45 pieces of 32L 3mm original LEGO rigid hoses in this build. Using alternative lengths is possible but also rigid hoses from other suppliers like Modular in Germany or McMaster-Carr the U.S.A. is possible. The alternative hoses behave differently to bending and may require a brass insert to keep them in place. Links in the comments.
