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.

    I’ve got an education in Chem E, and biomolecular engineering. And Im an engineer in the hyrdo-carbon polymer (plastic/rubber) business. He’ll be no worse then all of us really.

    I personally wouldn’t recommend using printed pla for anything food related. But if you want to be realistic , if you 3d print, you have this stuff in your body through cross-contamination consumption and your lungs from mass transfer. (If you can smell a chemical, it’s in your blood stream)

    In the grand scheme of things, the dude will be fine.

      Gosh the internet is exhausting when people think they’re saving someone’s life. My house is literally made of asbestos, radioactive isotopes are in our teeth now from nuclear testing, every single thing in the world if you live anywhere near a road is coated in a layer of motor oil (cleaning that stuff to stop darkening during electron microscopy required pirhana solution and a 3 day bake and pump), the dust in your house is not insignificantly vulcanised rubber from car tyres, lead glass wine glasses leech lead…

      we live in a world of poisons, it’s all about dose. Eating soup from a 3d printed bowl (or any plastic, I refuse to store food in it these days) is pretty unwise but it’s not like my 3d printer is made or arsenic and demons. I bet most of these chucklefucks touch 3d printed items and or wrench on their printers and don’t wash their hands before eating.

      Fuck man, your talcum powder is scraping plastic from the inside of the bottle and then you shake that shit in the air and apply it to children. A 3d printed funnel for try soft powder isn’t a bomb haha.
