I have seen one made of 10mm PVC pipe.
It had a T Section then 2 x 90's coming off each only about an inch of Pipe between.
Pretty sure he had 2 rubber stoppers on the end of each of the 90 Degree ends too.
Only thing I cant remember is how it was attached to shaft.
Probably $5 worth of bits from Bunnings or I could make them and charge $49.95
Hope That helps. I don't normally have too many drama's except with elliptical coil, that will not lay on the heel of the coil as there is no V section cut out. The other coils sit in that V section pretty good usually. Except hills, Then I just lay it facing down/up hill, I have it roll away on me once in Ararat on a particularly steep hill. . LOL
Cheers
