Waring blender jar retainer ring

The ring that holds the blades onto the bottom of a glass blender jar. Waring/Hamilton Beach brand. Not guaranteed to fit on yours - but has been successfully printed and used on mine (see photo). No leaks. Threads not perfect, but good enough. Will print without supports due to large chamfer in lower ring segment, which shouldn't interfere with motor and should greatly increase strength of final part... which should be good, as I'm tired of the OEM ones breaking about once a year.
