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.

He could just run a flame on it to melt whispy plastic strands down

Do you really thing that coffee grounds brushing up on something sheds significant amounts compared to like all the plastic you touch and then eat after not washing your hands? Or the Teflon in the rain on our crops? or storing food in plastic containers particularly during heating or freezing?

I'd be more concerned about takeway coming in shitty plastic containers that stain (indicating mixing on a molecular level) than coffee grounds touching a piece of PLA.

Yes, absolutely. Coffee grounds rubbing up against rough 3d printed plastic is going to act like little grinders pulling off bits of of plastic directly into the grounds.

Not to say that we all haven’t already lost the microplastics speed run. I am concerned about the things you listed, but yeah, I wouldn’t want anything 3d prone to be so close to so many small hard moving pieces of food.

3d printed plastic isn't much worse than other plastic. The grinds aren't under any force.

Have a look at a printed part under SEM and you'll see it's quite smooth and cohesive. Coffee grounds are light and fluffy, they don't grind plastic.

I think you're not basing this on any scientific investigation.

To each their own I suppose
