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.
So usually id agree that 3d prints shouldn’t be used for food, but this is a coffee hopper, they’re made from plastic already and I guarantee you the ones we used at Starbucks didn’t get that clean either, it’s fine, just sand it and get rid of those hairs
Yeah you need moisture for decay. Tiny fines might eventually go rancid in tiny pores and taste or smell a little bad but idk. She’ll be right.
Like it’s not like I clean the burrs that grind the beans much so if rotting was a problem I’d be dead already.
I use some supposedly food grade filament with a stainless nozzle and dedicated extruder, and after initial finishing they get a dip in food grade epoxy. I only made star wars and penis shaped cookie cutters though.
