• coupling the accessory to the attachment;
• passing the outer portion of the projection through the aperture defined in the first wall and into the first portion of the slot;
• rotating the attachment relative to the projection with the outer portion of the projection located in the first portion of the slot thereby aligning the projection to be inserted into the second portion of the slot;
• and
• locating the outer portion of the projection in the second portion of the slot with the outer portion configured relative to the retaining feature such that the retaining feature deters removal of the projection from the second portion of the slot into the first portion of the slot.
