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.
Yeah there is a way to say “this is a bad idea” without microbes tests. This is a bad idea, plain and simple. Just because you want to say otherwise, doesn’t mean you are right. It’s simply not food safe.
Oh you’re being a wowser.
So food safe is a phrase averaging a series of concepts. I agree it is tremendously unwise to say eat soup repeatedly out of a 3d printed bowl because of inability to clean it properly and leaching of contaminates.
It’s probably not very dangerous to eat peanuts once out of a 3d printed bowl because there’s no liquid to leech shit through and you’re not relying on washing it.
you need to think about the underlying mechanisms of things. If you don’t know anything then abundant caution is wise, but you should probably couple it with humility.
Leeching through solids is the only real concern here and I probably get orders of magnitude more heavy metals from my tap water (which are still safe limits) or VOCs from the plastic decaying slowly in the soil that grows my veggies (all soil on earth is contaminated at this point, but I grow next to farmers and lemme tell ya nobody hates the environment like farmers).
Chill out about your microbes already. The world is full of them and other micro-organisms that don’t harm you.
