Another approach that doesn't require the macaroni but should be
almost as good is to simply use the 2x2 rounds as strengtheners.
Since they stick together with the studs and also have an axle hole
down the middle, you could use them to prevent the twisting action
from damaging the axle. You could use regular bearings and gears
without as much risk of damaging the axle.
