Improved Eye Wash Cup Bottle Adapter

thingiverse

This jam fits into onto most disposable water bottles. It's designed to wash chemicals or foreign objects away from the sides and tear ducts of the eye. It has a spray profile similar to the "Sabre" eye cup. This improves on previous printable eye cup washers which indiscriminately washed the center of the eye, which can push harmful chemicals down the tear ducts into the sinuses and respiratory system. It allows the user to self-administer an eye wash with impaired vision, as the side fins prevent it from being used backwards, which otherwise might send contaminated water near the nose or mouth of the patient. No supports needed, includes its own snap off printing support.
