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).
I know way more than you realize. As I said before - you do you. It won’t be me who ends up drinking plastic.
It’s interesting that previously you said bacteria and now you say plastic. You know a lot, so enlighten the rest of us. What’s the concern here? As others have pointed out, coffee hoppers are rarely cleaned by most people, and this never gets wet and mostly handles dry whole beans with a little bit of dry bean dust. PLA is theoretically food safe as a material itself (and used in plastic utensils and containers). What are we missing? Please explain thoroughly in a single long post, not a quip because too many of us aren’t understanding from short quips.
