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.
A lighter will tidy up the stringing without making the mess that sandpaper will. Just don’t linger too long or the part will warp. It should take less than a second to make the strings disappear with a lighter.
Hot a air station, if you have one, will also do wonders here. I suspect an adjustable hot air gun would also probably work, but those things can put out some serious heat so be careful.
I actually use a Lexivon torch, and move quickly. Lots of heat in a precise location for a short amount of time.
