This funnel based marble run allows up to three players can drop in head to head to see who can stay orbiting the funnel the longest.  Alternately you can see who gets the most marbles in their section.  Or use it like a magic 8 ball.  Experiment and have some FUN. 

My longest run so far is 9 seconds, it is longer that a bull ride and only slightly less exciting.

The only part that I used supports on was the ramps as they were printed on their side.

I have added the Fusion file for the design if you would like to experiment with the design.
