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！

2024.12.30 Updated the bearingless version

• This 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 :

1. 608 bearing 2x （Bearingless version available for download）
2. Bambu marbles 14mm（ZB001）
3. M3 × 10mm cup head screw 15x
4. M3 × 6mm cup head screw 5x
5. M2.5 × 10mm cup head screw 1x

Some precautions:

1. It is designed to be rotated counterclockwise with the right hand grip, but can also be rotated clockwise.
2. When printing large models, try to apply glue or choose PETG material.
3. Please use the computer to open the 3mf file for printing. Printing directly from the mobile phone may fail.
4. Print the logo on the first disk first, then choose "Disc" in the object to continue printing.
5. The text part can be colored with acrylic pen or paint pen, and paint pen has better effect.
6. If the handle is loose, you can apply some glue.
