It’a detained by magnets so it doesn’t get in the basket and interfere with spreading out the grounds. Needs a clean up with a lick of sandpaper, pretty stupid but these things cost like 50 bucks /shrug
EDIT: appreciate all the concern for my health, it touches dry coffee grounds. I agree that if it got wet there’d be health problems but unless it gets real humid there’s just no opportunity for decay. As for random leaching same diff, without heat and wet it’s not really a concern.
That said I probably will seal an improved design, this is just a test piece.
I’ve been meaning to make one that molds to my grinder to prevent grinds flying all over the counter.
Just FYI, you can find metal dosing rings with magnets for as low as $3 on AliExpress. I’m sure yours fits better though!
Huh, didn’t consider aliexpress. I have an old lever machine with a non standard basket size (49 mm or something) so idk if they exist for it. I can see one with a brief search, but it protrudes down into the basket to locate itself which is a bit inelegant.
