Very nice. Are you willing to sell a finished product? Theres nothing on the market and im not motivated to print myself. If so, i may buy multiple for me and friends. Thx
Edit:Still working on it - I'm waiting for a part to finally be able to sell it (I want to sell a slightly modified version so that the bolts are extra strong by using some metal inserts). Should be ready this week. Thank you! I'm currently working on that. Check back in a few days if you want or write me on IG: dubios42

Thanks! Understandably, in terms of micro- and nanoplastics, this is probably as problematic/unproblematic as with store-bought plastic products (if done right), but if the print is not cleaned properly, larger pieces of plastic (which are still visible) can fall off, but this is avoidable by cleaning the print properly - especially if it is coated. However, if you print it yourself, you have control over the material used and can use very high-quality, food-approved filament.
i'm so impressed by the amount of work and details in description you put into this project thank you so much! can you add one for cafelat robot basket as it's acts as brew chamber also, i'd like send it to be printed for me through 3d printing service and i don't have the knowledge to edit a 3d file unfortunately
@@g33ks55 No problem, the 57mm version should fit perfectly, and the 58mm version will definitely fit. A version for 57.5mm probably won't be necessary. Just try it out, and if it doesn't fit, feel free to reach out again.
Super cool! I did see instructions on the Printables page to make the print as food safe as possible, but I am still not sure if it will be. I am also not sure if a bi-metal heatbreak is safe, and I still can't find a stainless steel nozzle for my Spider hotend...
Thank you! Yes, I actually have an extra stainless steel nozzle that I use exclusively for food-safe filaments - can't help you with the spider printer. Since I also sell the shaker, I've looked into the subject in depth and can say that, maybe it will help you: The main problem with 3D printing is the small grooves between the individual print layers, where bacteria can accumulate more easily. But since we're talking about coffee here and not slightly putrefying food, this should hardly be a problem, even if you don't sand the shaker (otherwise you would also have enormous problems with the coffee grinders themselves, as they also have places that you can't really get clean). Of course, you can remove most of these grooves by sanding them down if you are still worried. You could also apply a food-safe coating. On the versions I sell, I apply such a coating, which closes the very last gaps and also serves as a non-stick coating (foodsafe Diamant dichtol AMS, but is quite expensive). Maybe I will make a video about this. Alternatively, you can of course also use epoxy resin, but this is no longer food-safe if it breaks. To summarize: Personally, I don't see a problem with ground coffee as long as you use food-grade filament and a suitable print nozzle. If the shaker was for milk or something similar, it would of course be a different story. But in the end, you have to decide for yourself :) Edit: I have just watched the video by Slant 3D, he briefly discusses the print nozzle and food safety topic, maybe that will help you too: th-cam.com/video/LAGc4GKDeoU/w-d-xo.htmlsi=bDUpFiykWRoudKbV&t=1618
Thanks, this is really nice! Been thinking about a shaker, but now that there's a printable option, I'll give it a go. Have you tried attempting acetone vapor smoothing? This may be a good alternative to sanding.
Had fun with it, thanks :D I can't print ABS (yet), but I was thinking of doing it with epoxy resin - would of course give the ultimate result. Feel free to try it out yourself, I am happy about everyone who contributes! Of course I have to say that with this shaker in particular, the approach was to do as little as possible after printing to get a good result so that everyone can participate.

Thank you for your interest! I only sell the shaker on Ko-fi, as it is very nerdy, and unfortunately there is no function for a reminder on Ko-fi. But I'm currently offering the non-sanded versions again - it's hard to say when I'll offer sanded versions again, as I can hardly find the time to make them at the moment.
very nice my dude, very nice. I printed a cup that goes over the cup of my hand grinder, and i go shakey shakey. do you think the donut thing makes a difference, as opposed to simply shaking?
I am currently trying to answer this question objectively with a few measurements of the TDS value. There are already tests by others, such as Lance Hedrick, which show that the blind shaker gives a better result than normal shaking. This is probably due to the fact that when filling the portafilter, the ground material is first filled in the middle. That's why I have adapted my shaker for many sizes, as this effect would otherwise be lost for smaller portafilter sizes.
Perhaps I am misunderstanding here, but doesn't the linked paper show that a paper filter under puck is already more than enough to fix the underextraction issue? In which case why would anyone prefer buying/printing and using an extra gadget instead of sticking with a more widely available wdt+paper filter routine?
No, of course you can do that too! But the other advantages of the shaker are then lost: The shaker combines all of this: Dosing cup, dosing ring so that there is no souring, very even extraction (- I also used the WDT with an Umikot before, also visible on my channel, but especially with the Flair I clearly notice that the shaker principle leads to a more reliable result than the WDT -), you don't have any additional consumables, i.e. the round filter papers, which you would have to cut to size yourself depending on the sieve size. But in the end, it's all about being satisfied with your espresso and everyone has to decide for themselves how they prefer to do it.

Very cool. I think there are too many coffee gadgets that overcomplicate the puck preparation. To streamline, maybe for your V2 or a production product, why not have the donut double as a spring loaded level and tamper. This would speed things up considerably. Grind right into the donut. Place ontop of your basket, Pull the plug out and then tamp with perfect pressure, level and consistency. Add a magnet to the dosing cup too, so that it clings on to the filter basket nicely.
@dubios42 Not at all, your video shows you using an orbital distribution tool directly after discharging from the shaker to the portafilter. Lance has proven by meticulous experimentation that this practice is counterproductive.
@@lezc3733 I see what you mean but this are two complete different videos. The scene with the umikot (wdt tool) is only meant to underline what I am saying at that moment. Here is the original video with the umikot (wdt tool): th-cam.com/video/SL9MbnI4Etk/w-d-xo.htmlsi=plr0H3VBFpRfLRdB
@dubios42 Guess I just got confused by the cut, nice shaker though. Not a big fan of the Umikot myself, I prefer a cheapo Amazon WDT with my Niche, and just a shake and tamp with my Eureka.
@@lezc3733 Thank you! Yes, understandable, it wasn't the cleverest edit from me :D Sounds good, everyone as they like it and the main thing is that you like it in the end. I just like to develop things, try them out and experiment
This 3D model has the most convoluted and unnecessarily complicated description ever. Why wouldn't you settle for a few basics instead of endless variants and versions with no apparent purpose or reason?
I'm a fan of detailed descriptions, so that's what I do, and anyone who knows their way around can just start printing. There aren't actually different variants of the shaker, just for different portafilter sizes and that makes a lot of sense here to work well with every portafilter size. Sure, there are different variants for the bolts, but the first variant is the one I recommend and that's what I've written. The others fulfill other requirements and that is also stated. Hope this helps.

Thanks, yes!
Is vapor smoothing a safe alternative to sanding?
It depends very much on which solutions you use and whether and how they have a lasting effect on the plastic. So it's best to do your own research :)

If you want to control the static build-up just wet the beans with a spray of water before grinding.
Yes of course
If you WDT after shaking it completely defeats the objective, have a look at the data Lance collected.
You are correct :D
I think you misheard me, it's about RDT before grinding. I don't even mention WDT in the video
