Try putting the handle on the bottom instead of the top. Might be a better angle of attack and no supports. Kind of like a front loader. Great video!

As someone who considers coffee to be a medicinal requirement I have to suggest you go by weight instead of volume if you truly want a consistent cup. Then again I prefer my coffee so strong i need to chew it so if I ever suspect I might not have added enough an extra full scoop always fixes it right up. 😁

This is the case of you're not supposed to do it... but also it's what one might describe as a low-risk violation in this case, because it's touching dry particulate. What is to be said is that you don't know what's in your PLA. Like sure the PLA resin itself is safe, there's really only one primary source for virgin pellets and they're good, but then you have masterbatch, which has mystery soot and mystery EVA in it, and all sorts of mystery junk, processed on mystery equipment which ran a mystery material just prior; and then you're running it through a printer where parts, contacting the filament and the melt, are made out of mystery steel and mystery brass, and you don't know whether they emit heavy metals. All the while the inside of your nozzle is coated in mystery residue, including ABS, which is bad news indeed. You absolutely DO NOT make that scoop from ABS, because it emits uncured styrene (see my previous-week comment, polymerisation inhibition), poison, bad, and you're sticking that scoop into your coffee grinds into an enclosed container and keeping it there for who knows how long. ABS was for the longest time not even eligible to receive FDA certification, because synthesis process does not guarantee (to put it mildly) that it's safe, as opposed to the majority of food-contact polymers. Now some manufacturer pleaded with FDA and received permission to engage certification process but i don't know how it played out, they promise they figured out some way to make it safe, one manufacturer, maybe two, not the rest of them, but i'm very very dubious on this very idea. I suggest instead coating the print. One coating that has been suggested is food or pharmaceutical grade shellac. I think i got this from a Taiwanese KZbinr but i won't be able to remember who it was. Another obvious candidate is epoxy, and i do have a local chemical manufacturer whose industrial-use epoxy has been certified for use in drinking water tanks, and they also sell a retail version of the same product, though the retail version of course doesn't come with cert but it's identical. But wrong end of planet, you'll have to find your own. You'll also have to inquire about cure conditions that promise to make it safe, because right up front it's very much not, very dangerous, and it can take some time to post-cure and fully bind its poison.

As a coffee enthusiast I highly recommend you get yourself a decent low-end burr grinder ($200-300) , use weight instead of volume and do single-dosage grinds. Grinding ahead of time you always introduce moisture and oxidation in the process. While heads and shoulders above any instant machine, the only way to truly elevate your coffee is single-dosing, IMO.

Loving your practical prints. Your channel (and your review of the A1 printer) was what finally sold me on buying a 3D printer myself. My A1 is ordered and will hopefully be here around the end of January. One thing that has turned me away from joining the 3D printing community earlier was constantly seeing little action figures/decorative prints on YT/Thingverse and not seeing enough practical prints that you can make to solve practical problems. I have nothing against those type of prints, they just aren't something that I am interested in, but it seems like a lot of the content out there is focused on them. Sure, 3D printing a coffee scoop isn't a lifechanging QOL print, but it is an example of how you can turn a fun hobby into a way to solve life's little - like brewing the perfect cup of coffee. :P I particularly liked how you demonstrated and explained your build process and showed your 'failed' prints, even explaining how rotating the print so the handle was closer to the exhaust fan helped improve the sturdiness and quality of the print. One thing that has annoyed me is scooping food for my 2 large breed dogs. As it is right now, my wife and I measure out their food once in the morning for the day in 1c increments. I get kind of annoyed by how tedious it is scooping 4c of food times 2 dogs every day. With 3D printing, I will be able to create a scoop that will allow me to scoop once or twice per dog and leave the scoop in their respective food bins! I appreciate the warning of 3D printed parts not necessarily being food safe, so I will have to do some reading on if this is a good idea, and maybe look into one of the the other commenters suggestion on coating the material in a resin of some sort. After all, I wouldn't want to poison my dogs because I was too annoyed to scoop their food with a measuring cup :P. Thanks for the videos, I look forward to watching more of them in the future.

The other considerations are 1. microplastics. The coffee grinds are going to be abrasive on the plastic scoop. If you were just scooping beans and single-dose grinding, sure, no worries. 2. Coffee oils and particles getting into the layers. More-so worried about rancid coffee oils, which make coffee taste bad. Replacing scoop will help, since you can't really clean it.

@FunctionalPrintFriday 11 ай бұрын

fair point. I'll probably just re-print once or twice a year.

@electronsmove 11 ай бұрын

I am surprised you didn't model the container in SU first, then make the scoop fit the interior shape of the container. Then scale it to get the right volume. Then print it. The corner you added should have been pulled out from the original scoop not cut back into it which reduced the volume. The formula for the volume of the complex scoop is to fill it with water and pour it in a measured container.

@logicalfundy 11 ай бұрын

Going to voice my agreement with @SianaGearz - ABS is a hard no, it's worse than PLA. My suggestion is PETG with a food safe coating. PETG should be easier to clean as it can handle more heat than PLA, plus it's mostly food safe to begin with, you just need to take it the rest of the way with a coating.

I think you’ll be fine with the PLA in this use case. Matter of fact I’d rather use your coffee scoop then the never cleaned Keurig machine in 90% of the offices/waiting rooms across the world. When you wipe them out and paper towel your using is yellow or pink its almost certainly Serratia marcescens and Aureobasidium pullulans bacterias. I mean coffee makes you need to goto the bathroom, however if you’re doubled over sprinting to the toilet….probably not just the coffee. I used to do pour over but got a bean to cup machine I’ve been in love with (once it’s dialed in). Just add beans and water and walk away.

There's a lot of variety in the electric burr market, but look for all-metal parts and a decent amount of grind sizes. There are a number of manual burr grinders that are much cheaper and perform great, like the Timemore CS2. When looking for a manual grinder, look for one with a double bearing central axis, which prevents burr wobble.
