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.
This is good advice.
On the bright side for OP, his part should (hopefully) only come into contact with dry coffee grounds so some of those concerns are lessened.
In other applications – sealant or not – I can only imagine pouring hot coffee over a PLA part would not be a recipe for success…
Microplastic speed run
He could just run a flame on it to melt whispy plastic strands down
I know it’s probably sacrilege, but I avoid the need for one of these by grinding half a dose, tamping a bit then grinding the rest and finishing the tamp. I’m using a Breville Barista Express so couldn’t (easily) use one of these even if I wanted to.
I’m curious how you retain the magnets in it? Are they printed in, or mechanically added later? (I know very little about 3d printing, this just came up in my top-6-hour feed)
I haven’t done much with magnets, but I saw one model where you pause the print halfway through, drop magnets into the holes, then continue the print and they get sealed in Amontillado-style.
Pop the magnets into the paused print.
The magnets: "Hahaha. This is a fine joke, good sir!’
Resume print
Magnets: “Yes, a very funny joke indeed. Wait, sir, where are you going! Sir! SIR!!”
Walk away knowing that neither you nor anyone else will see those magnets again
Oh God imagine being 3d printed alive into your casket
Worst part is it taking forever for it to print the casket around you, and you’re just lying there unable to do shit and just watch the casket close around you in ultra slow-mo. Like being buried alive with a tea-spoon for a shovel.
