This device zigzags balls vertically / in a spiral, using three kinds of component : base, upper, and tunnel. 
The spacing between the steps is 2 cm.

All components can be stacked on other components or regular tiles. 

I recommend printing the upper part for vertical zigzag as shown in the picture!
Apparently support for the ring portion is mandatory. 

Other parts can be printed without support…but I rather use support setting the threshold to 75 degrees. 

I made 2 sizes for the ring - If you find normal ones too small, use bigger.
I use normal rings for the base and tunnel, and a bigger ring for the upper part. 

p.s.
In case of excessive shaking of each module, Gravitrax balls can be used as weights (except the vertical upper part). Although it might not be used very often...
