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.
Please keep in mind that you need to seal that print before you use it with food. Because of the layers, there’s are a ton of places for dirt and bacteria to hide that are impossible to clean. Additionally, depending on what kind of nozzle you used, heavy metals can end up in your print which you don’t want to then leech into your coffee. General advice is to just not use 3d prints first good, but if you really want to you should coat them in a food safe epoxy before using.
