wherein each of the first tray and the second tray comprises a chamber wall having (i) an inner surface that defines the plurality of ice chambers and (ii) an outer surface,
wherein the tray opening is disposed above the chamber wall,
wherein at least a portion of the outer surface of the chamber wall is exposed, through the tray opening, to the cool air passing through the first guide to thereby come in contact with the cool air passing through the first guide, and
