Great effort went into creating each bracelet size. Instead of simply scaling an original model, each gear was varied slightly in its size. The outer diameter of the gears varies between bracelet sizes by as much as 0.5 inches. By adjusting the different sizes with this method the minimum wall thickness for each bracelet is the same, meaning one size won't be considerably stronger or weaker than another. Lastly, the size of the gear teeth was kept the same, and number of teeth varied. Again this leads to a much more consistent design between all of the sizes.
