Ice Cube Maker

We have never had a refrigerator with an ice cube maker before.  It makes a knocking noise when the ice cubes fall into the tray and I always think the knocking is someone at the door.  Barb uses the ice cubes to keep her lemon water cold when she goes out to play pickleball but the top of the bottle that she uses is quite small and the ice cubes are quite large.  So she is always dropping the ice cubes all over the floor.
