3D Printed Perfect Coffee Scoop

[@Enjoymentboy]

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. 😁

[@haydenc2742]

If the spoon stands up on it's own...it's PERFECT! (gunny approved ;) )

[@Flumphinator]

Watch out for your heart health bro. I used to cram two iced coffees a day, and I have heart problems now. May have been predisposed before, but the huge coffee intake exacerbated it for sure. Caffeinate responsibly, lol.

[@Enjoymentboy]

@@Flumphinator I'm well past worrying about that. TBH I'd rather have a short life with copious amounts of coffee than a longer life without it. I still have my 2 french press pots a day and my BP is regularly 120/70 with a resting heart rate of 70...and that's after I walk to the clinic where I donate plasma 2x weekly. I walk 12km daily (to and from work). I'm healthy...much healthier than most men my age...but I do honestly appreciate your words and your consideration. I'm good. ☺

[@FunctionalPrintFriday]

lol, I just commented the same thing to someone else :P (spoon standing)

[@ishepard2]

I second this.

[@CandidProle]

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!

[@FunctionalPrintFriday]

interesting idea, thx

[@johnparker2636]

Yep- I was going to suggest that too. Also have the handle pointing straight up ( parallel to the side wall when in use).

[@jonbbidwell]

I know how many people would say that this problem is a trivial one. I totally understand where you’re coming from. I like solutions to problems that I have to make my life easier.

[@FunctionalPrintFriday]

ohh it's totally 'trivial', but the frequency is high, so I think it was worth it

[@billbyrd9845]

The only justification I need for 3D printing things is... it's fun!

[@actualreplyguy]

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.

[@andrewgueguen8767]

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.

[@foam27]

You're so lucky you are starting with the A1. All of us had to thru years of crappy software/machines before Bambu Lab. You'll love it. Hope you got the AMS!

[@andrewgueguen8767]

@@foam27 I did get the AMS. I read a post somewhere saying that you can use the AMS to continue a print if your filament runs out. Sounds like a good way to use up almost dead rolls of filament if I don't care about the colour. :P

[@SianaGearz]

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.

​@@peircedancheck out iglidus i151 and i181 (the higher temp version) from igus. Those are rated to be used in food production by the eu and the fda.

[@haydenc2742]

Back rake angle on the side of the scoop (similar to the cutting tool for lathes, the side contacting the cylinder needs to be tapered back to prevent rubbing) Very cool design! Keep em coming!!!!

[@clockworkvanhellsing372]

Iglidur i151filament from igus is rated to be in contact with food, at least in europe. Without watching the video: If you are unsure, go with the food rated filament. (There ,ay be others too, that i just don't know about). I181 is a higher temperature version, so it may be able to be washed propperly.

[@JimSmith001]

Suggestion: save yourself a lot of time in iteration of design by first making yourself papercard mockups to get the geometry close before even going to CAD.

[@SianaGearz]

CADboard. CAD = Cardboard Aided Design.

[@thedolenorway]

I personally would probably spend a lot more time trying to make paper mockups than I would redesigning something in CAD for most projects. 😂🙈

[@spasecookee]

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]

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

[@onerazz3115]

I have been using my 3 D Printed Coffee scoop for over 2 year maybe 3 years and every thing is just fine with us. No problems.

[@FunctionalPrintFriday]

thx for sharing

[@jaymax97]

I love this series, makes me wanna design things for my own life😂

[@robertshuler7269]

Vapor smoothing and a food safe resin coating. Scoop in white, resin coating in a different colour. If you see any white spots poking through time for a new one.

[@reinux]

There's some promising research that says bacteria doesn't get into printed parts all that much. Out of an abundance of caution, I'm still holding off on using prints for liquids or anything too abrasive/caustic, but I'm optimistic. Cool channel!

[@FunctionalPrintFriday]

thx!

[@logicalfundy]

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.

[@a-bell]

what kind of coating do you use that's food safe?

[@logicalfundy]

@@a-bell haven't made a print that contacts food directly, so I'm mostly going on research I've done. It's on my TODO list though to find something because I'd like to make similar prints sometime.

[@LdHrothgar]

That is a LOT of coffee for a single cup...

[@FunctionalPrintFriday]

If the spoon doesn't stay standing, it's not strong enough :P

[@cynic5581]

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.

[@FunctionalPrintFriday]

it's so true, there's some places I go into that I'm just like nahhhhhhhhhhhh, that water tank is more like an aquarium

[@electronsmove]

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.

[@ChozoSR388]

If you're interested, there's approx. 9g-12g of ground coffee in a K-Cup. 9g equates to about a tablespoon and a half. 12g is 2 tablespoons.

[@FunctionalPrintFriday]

thx

[@anbu94]

Awesome design for a scoop that solved a unique problem. Dang, my comment had 1 like 🤣

[@mitchellvanwagoner8119]

You could have filled the old scoop with water then weighed the water to get the volume, no extra steps with the transparent cylinder. But what works works, so doesn't even matter!

[@Goosefang]

The ideal scenario would be grinding immediately before brewing and weighing the beans and water 😳

[@tomwagemans1872]

I'm new to 3D printing so I was doing some research on filament. I came across an anti bacterial pla which should kill 99% off the bacteria. It didn't mentioned foodsafe. Unfortunately I forget the brand.

[@henrymach]

You could design the handle in a way that it doesn't need supports

[@jeffsmith7740]

To up your coffee game, measure weight not volume. Grams coffee per grams water. 1/16 is a starting point. Just found your channel. Good stuff.

[@75keg75]

24:17 spray with a food safe epoxy to seal the plastic particles from breaking off and you’ll be sweet permanently. Even cooking cutter people can do that too.. . Could you print face down so the dish is the over hand rather than handle printing in nowhere.

[@ladyfarah]

You really should measure by weight. The volume of the individual grounds will vary and it may clump and be packed together changing the density.

[@stevendunn264]

I like this print. Can you make a pour over cup coffee filter holder to go on top of a cup. What Filiment?

[@FunctionalPrintFriday]

I've tried it on all the top layers and not a fan of the look personally, but I'm loving exploiting it to get contrast

I love your series. I recently subscribed because: I have been using Sketchup for over 20 years making simple furniture designs, I am also a woodworker, I am also more interested in practical, functional 3D printed designs instead of trinkets, I am designing my own functional 3D printed parts too! Question: how do you go from an .skp file to an .stl file? I am old school and using Sketch 2017. Thanks

[@FunctionalPrintFriday]

I use 2017 make as well. There's an STL export plugin for it

[@kippie80]

HI, I'm a regular on your channel now. Question : How do you get good STL files from Sketchup? I've tried and they are not completely closed and fail in the slicer.

[@rexgoodheart3471]

I use a Sketchup extension named Solids Inspector². It is invaluable. It checks for hidden faces, reversed faces, surface holes, etc.

[@FunctionalPrintFriday]

I've had pretty good luck. I do occasionally get duplicated triangles (especially for imported geometry), but otherwise as long as I'm "thinking solid" when I design, it's been good

[@kippie80]

[@bjrnsrensen8456]

I love this series, but frankly, the best solution to this problem is a scale. No microplastics in your coffee and consistent amounts every time. Home grinders, especially blade ones, aren't consistent, so different grinds will yield different volumes.

Is there a grinder you recommend? I've been using a cheap cuisinart DBM-8P1 and it's been pretty good, but I want to upgrade at some point

@@mrfoameruk Yes, everyone who is serious about coffee.

[@bjrnsrensen8456]

​@@FunctionalPrintFriday I'm quite happy with my Baratza Encore and would recommend it, especially for filter coffee since it can grind a lot at a time. 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.

Keurig, will never understand why people like them so much. For the amount you spend on the pods a year you can buy two high end automatic espresso machines that grinds your coffee and brews it with the push of a button. Spent $900 on a Delonghi espresso machine 10 years ago, great frikkin' investment......an no waste, other than used grounds.
