The tappet of the Surefeed Sealed Pet Bowl is a bit weak, becomes brittle over the time and breaks after a few years. This part can replace this tappet making the bowl working again. For better stability and to prevent the need of supports I took the arm and the axle apart. So they can be printed in the best position for a higher strength. It looks not so sophisticated like the original part but is much stronger.
