Marble Run V2

The marble run has always been one of the favorite toys of children. I have previously made a 25mm marble version and a 10mm magnetic marble version. This time, I modified the size and some parts of the magnetic marble model to adapt to the 14mm standard marbles of Bambu(ZB001). The reason for making a manual version is that I want children to have a certain sense of participation when playing, rather than just watching with their eyes after turning on the switch, which is boring.Hope the kids have fun！Boost MeThank you for your support！2024.12.30 Updated the bearingless versionThis version changes the direction of rotation of the turntable. Hold the handle with your right hand and rotate it clockwise. Counterclockwise rotation does not work. The old version can run in both directions.Assembly BOM :608 bearing 2x （Bearingless version available for download）Bambu marbles 14mm（ZB001）M3 × 10mm cup head screw 15xM3 × 6mm cup head screw 5xM2.5 × 10mm cup head screw 1xSome precautions:It is
