Weight driven marble run MarbleRok

Weight or gravity driven marble run. The weight on a left cord is driving the marbles to the top. When the marble is falling on a switch "button", the wheel makes one step turn. With 1200mm long cord, the mechanisem is working about 10min. Then you pull the left cord and the mechanisem is wound up.

All you need is: -11x steel ball with diameter 10mm

-2x string with length of 1200mm (string ticknes aprox. 1mm, synthetic)

-200g weight


Use step file. I loaded just one stl file, that i can publish model. All other parts are in step. Best way is just to download step-assembley.
In the 3d model the numbers behind the each name are the version of saved model. Assembley has a number 782. That meens that i saved this model 782x.
