Forty-millimeter funnel shaped for the windshield-washer filler opening. The creator shows the physical funnel seated in the fill neck from two angles and designed it to print support-free with the larger end upward. This is a service accessory rather than the reservoir, filler neck, or cap, so no parent component number is assigned. Confirm the neck fit before pouring and keep debris and incompatible fluids out of the washer system.
