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.
Hey, that’s neat! I use a scrap piece from a previous employer. It’s a 2inch tall stainless steel combiner ring. Definitely not as cool as yours and definitely not light enough for magnetic holds. You win lol
