On each axle I used four 3-long linkarms. The link arms are positioned in such a
way that they never rub against eachother. I have made another link-arm passer
that uses one 4-long linkarm per axle. The linkarms do rub slightly as they pass
but I've been able to adjust it so that it does not catch.

I did a quick test and they soccer balls do work. Overall I think soccer balls
are easier to use than marbles. I have spent many hours finding and sorting
marbles that have a diameter that is less than a 2x2 brick...but marbles have
nicer weight and colour.
