You have buyer waiting already, :D . Exelent work and desing
Hopefully you remember to show love to your early supporters 😁
I signed up for your email notifications because I think you're onto something that's going to shake up the extrusion printing industry in a big way! 👍
Question: Have you already made an efficient system for recycling/shredding filament for reusable pellets as well?
Cnckitchen has a few good ones as does teachingtech if I remember right
already did that
I noticed there is no heat break in this system, how long does it take to heat up before printing and how long was your longest print in testing?
Big companies make a simple idea look complicated to ask for a lot of money while wise guys like you make it really simple and cheaper and show that can it be done without a lot of mystery. This is the easiest subscription button click I have ever done. Very nice, hope some day I can use this.
Thank you for your warming words! ❤
What would you like to see next? 🙂
engineering isn’t the mystery. mass manufacturing is
Neither is a mystery. It's an art@@kleanish
Maybe the bucket you empty unused pellets into is itself a modular piece of the hopper so you don't have to keep transferring over and over, and loading the machine becomes easier with less risk of spilling pellets everywhere
There are some major flaws in your reasoning. The first is that you think one guy doing it for fun is somehow better than multiple teams of engineers. Another flaw is that simple does not equal the best or good, maybe the other companies solutions were more complicated for good reasons. A major flaw is thinking this is cheaper, one guy doing it and posting about his progress publicly will not have to worry much about the cost of their time whereas a company needs more engineers and needs to pay them high salaries which then gets passed on to the customer, this also seems to be just a prototype, so whilst it may work it may need significant work to make it producible on any reasonable scale which again takes time and money.
Also there was never any mystery about pellet extrusion if you did any research at all, injection moulding machines have extruded from pellets for decades. Likely the reason that companies haven’t focused on pellet extruders is because filament extruders are generally just better. There seems to be no benefit to direct pellet extrusion other than cost and when turning it into filament first it is easier to add colour or composites. With the method shown here it would be difficult to add anything into the plastic consistently. If you need to 3D print at large scale or want to reduce costs then you likely can afford to buy a filament extrusion machine and just buy pellets and turn them into your own filament and then use normal off the shelf printers. The cost of outfitting a large print farm with pellet extruders far outweighs the cost of just buying filament or your own filament extrusion machine.
This could legitametly be a million dollar idea, and for the value that it can and I believe will add to people's lives, I feel wholeheartedly that you should be rewarded for your phenomenal efforts. Thank you so much for taking the time to develop this product and share it with the world. I wish you nothing but 100% success, financially and beyond, with the launch of your invention!
This is not his idea. There are pellet 3D printers already
They are far from cheap though, did you even watch the video?@@romantashevRT
This isn't a million dollar idea however, there were 2 pellet extruders made in 2015 at different universities in Sweden. Both were small in this regard and one of them continued making industrial machines. Very much the same design as this, however this is a bit more well designed from what I would imagine would be a passion project and a lot more time :)
Umm, nobody sees the main flaw? Colors. These small extruders can not mix properly pigments into the material. That's why industrial extruders are huge.
@@romantashevRT and you can buy them from ali
If there wasn't an ocean seperating us, I would be actively throwing money at you. Thanks for the full assembly video, addressing some of the common failure points, and the engineering that went into using only common parts. Looking forward to putting together my own when this gets released!
It will be shipped internationally 🙂
And I will need one too
@@greenboy3d ich brauch das nicht... ich brauch das nicht... ICH BRAUCH DAS!!!
Fun fact. Using the same revolutionary technology that allows for us to watch a video of him from across an ocean, average folk like us can throw money across an ocean back at him.
This will make testing 3D prints so much easier since i can do more tests and I won't feel bad about using a large amount of supports anymoe. All the waste can be just ground down and reprinted.
Yes but you need to keep in mind ground print waste is not exactly same as original, while printing some substances which help make p4inting easy vaporize, so petg when ground isn't petg anymore, it's like printing pet, more stringy less forgiving
@@howabout2138Obviously _some_ plastics are going change properties once heated and cooled and not _every_ filament type is recyclable...
That doesn't change the fact that many filaments _are fully recyclable_ and with how common 3D-printers are getting, the ability to recycle even ½ of the plastics used will be *huge* in lowering the amount of plastic waste and environmental impacts of 3D-printing 💯👏
No no no no you can´t simply keep recyngling that crap over and over again, it´s not like a metal plastic degrades over time you will always have to add virgin material, probably at least 50%. But this opens up new possibilities, like color mixing, recycling, keeping material dry or drying it in real time etc.
Recyled materails test printing or print your going the sand smooth anyways sounds like a good idea for printer poop/fails seem like a interesting way to deal with it.
That is definitly the main goal with this, I only need to figure out a better, easier and cheaper, way of recycling failed prints back into pellets. What however would be revolutionary (which is also something no one even imagines about) Is that you actually could recycle you general home plastic waste like jogurt cups, bottles and so on... into usefull objects 🙂
This is by far the biggest advance i have seen in years ! And the dark truth is simple : price of the filament vs pellets …
A full métal hotend with more heating power can probably print almost any material at a fraction of the cost.
Keep this up !
Thank you for your warming words! ❤

@@greenboy3d how about carbon fiber nylon? The chopped fibers in a pellet can be longer than the ones in filament, leading to stronger parts.

@@chesshooligan1282 hahaha 😅
How's it possible that big companies like Prusa and Bambu don't have anyone prioritising this sort of fix? Because they'd lose money on selling filament? Perhaps this will be yet another gift of open source. If this tech takes off on cheaper printers, they big boys will be forced to adopt this ASAP to avoid a mass exodus from their machines. Brilliant!
I'd say more or less yeah. I mean filament printers are cheaper and easier to make. But for many places, they can cut printer costs by shifting their profits to the filament. Just like how you can buy an inkjet printer for $30, but the ink costs $50 despite costing only about $0.10 to make.
Filament is WAY less of a rip off than inkjet, though, so I don't mind the hit too much. But I would love to have an open source option like this in order to at least feel less wasteful, and can order materials cheaply and in bulk.
It wouldn't work for Bambu since it can't change colors.
exactly.
because companies thrive on "lifetime consumers" (aka. geniuses), not free thinking individuals who can see through the curtain on the stage (of life) who could potentially distrupt the game in a heartbeat if there is an unjustified markup in retail in any market to be balanced out. if a filament costs arms and legs compared to the raw material price this imbalance will sooner or later be resolved with.
The *entire movement* for "home-based 3D-printing" was started to make open-access small scale production & prototyping easily accessible for everyone and to allow home-based makers, engineers, & artists to be able to bring their own computer models to reality 💯
That's why I was starting to get really disheartened at seeing companies lean more into proprietary software/hardware and price-gatekeeping the best materials/newest technologies... 🤦
But seriously, you have resparked my passion/hope that 3D-printing can & will eventually reach its full potential as it was originally intended‼️😁👍
I'll do my best to achive what you mentioned :)
What would you like to see next? 🙂
@@greenboy3dPEEK for the price of polycarbonate
Nothing about 3D printing says it has been or is intended to be open source or open access, that is just what you want it to be. The point of home 3D printing is to allow people to 3D print at home, it doesn’t really matter if the printer is proprietary or open source. The first 3D printers weren’t open source and were never intended to be.
So what if more closed source companies came about? If you don’t want to use closed source then don’t use it, it is as simple as that. However you can’t deny that closed source printers are making 3D printing much more accessible, why haven’t open source printers done that yet? How is a company like Bambu Lab able to make better printers with more features that are easier to use for a better price than any open source company? If you want open source to compete then you need to help it compete, if you want the open source equivalent to a Bambu Lab printer then the open source printing community or a company need to make one. A lot of people seem to forget that open and closed source can coexist, we don’t need to choose one or the other and neither is inherently better or more moral than the other. You need to ask yourself though, why isn’t open source at the same level as closed source printers?
Some aspects I do agree with though, particularly in regards to patents. The patent system is broken and really needs fixed. We still need patents but patents for fast developing fields like 3D printing should be short, two years at the absolute maximum and you should only be able to patent implementations, not concepts.
@@conorstewart2214 Bro. Then entire home 3D printer industry started open source. Sure, 3D printing existed in industrial and high-end prototyping first. But that was inaccessible to anyone who didn't have hundreds of thousands to throw at it. The reason why so many of these companies and sub $1000 printers exist is because of open source. Just because Bambu or whatever doesn't share their design files doesn't mean they didn't lean heavily on existing open source technology to get their products out. Ever heard of Prusa? Makerbot? Ultimaker? Most of the tech that 3D printing companies that aren't open source sell (Creality, Bambu, etc) started with open source. They may not be using open source to produce their products, but they copied many of the innovations of others. Bed leveling tech (touch sensors, magnetic, etc), power failure recovery, slicer software, motion systems, etc all came from open source projects and companies.
Take the humble Ender 3 for example, a $250 printer. First off, they run marlin. Open source. The entire motion system is a copy of Prusa's i3. Open source. Bed leveling sensor, a copy of the BLTouch. Open source. OK, so they designed their own control board and extruder, big deal. The entire product and the very demand for it would not exist without Josef Prusa's original i3. And that wouldn't have existed without the RepRap movement, started by Dr. Adrian Bowyer.
The entire reason why this industry exists in a way that normal people can access it and use it is because a few people figured out how to do it cheaply and at home and shared that with the world. If that had not happened, I fully believe that 3D printing as a hobbyist industry would not exist. Without the maker community, only large business would be doing any type of 3D printing at a cost of tens of thousands at the very least.
@@conorstewart2214I agree on two facets
1 : open & closed source "can coexist", if you as a private entity want to make and sell something without telling people how it works that's your right. However, that doesn't mean it cant be socially or culturally discouraged, it just means you should have a legal right to do it. Calling someone random on the street a dickhead is a legal right, and it should be, but it still makes you an asshole.
2 : patents are broken. I'm dubious on the idea of patents in general, but I could be convinced they're a necessary evil to some extent. (Generally I fall more in line of the camp "if you don't want people to use products in certain ways, YOU can invest in trying to stop them, but the tax payers aren't your enforcers", so DRM, trade secrets, etc. are all fair game, but if someone leaks the code, reverse engineers it, cracks the DRM, etc. thats also fair game, thus things can reach a natural and stable equilibrium) With that said, I've seen some ludicrously simple patents that aren't even a design or design concept but just a vague idea, and they still don't expire for decades. IMO "vague idea" patents shouldn't last more than a year, "I can see the innovation there but thats pretty bloody simple" can last 2-3, "alright, yeah, thats fairly unique" ~5, and "holy shit, yeah, this is pretty huge and could be big" ~7.
Businesses getting to a market first already have an insane competitive first-move advantage and can grow their market niche by making their products better, you don't need two decades of forced exclusivity too. Esp. since many new ideas are fairly logical progressions based on the cultural collective unconscious. A lot of the "unique ideas" you had were probably had by dozens or hundreds of other people because they originate from the same core ideas currently prevalent in the cultural zeitgeist. In other words, chances are without a patent someone else would make it within a few years too, but with a patent they can't without engineering around your BS.
I mean christ imagine if Apple got a patent on the smart phone. No, not the iPhone, the smart phone. I've seen patents WAAAAAAY more far reaching then that, and yet if they did get that patent they would *_actually_* still have the monopoly spineless #RtR consumers claim they do, since that patent wouldn't expire until at least ~20 years after the first iPhone was released.
With that said, you are completely wrong about 3D printing. 3D printing as we know it today was and frankly still is borderline extremist open source. Starting ~2005 projects like the Reprap started going with the explicit goal of open sourcing and decentralizing manufacturing. In fact, this started before the patents for FDM even expired. (2009) Prior to this the idea of individuals, let alone average consumers, owning a 3d printer was fucking laughable. We're talking hundreds of thousands of dollars here, these were exclusively industry targeted devices.
3D printing is a market niche that was conceived, incubated, birthed, developed, educated, graduated, and is now getting a full career in Open Source. Additionally proprietary offerings rarely do much all that special, with open source offerings almost always being generally better except for, again, patents.
Closed source has a right to exist, but that doesn't make it good. If people are willing to buy what you are selling every party involved has a right to make that transaction, but that doesn't mean what you're selling is actually a good product or is even better than alternatives, it just means that, for one reason or another, your customer wants it and is willing to buy it. Eating 5 pounds of bacon is not a good idea, but you are just as free to sell 5 bounds of freshly cooked bacon as you are to buy and then consume 5 pounds of freshly cooked bacon. (Or buckets of cheese)

I can see why for hobbyist-level machines, manufacturers have little incentive to push for pellet printing - especially since they also usually sell filament spools themselves.
But for large print farms that go through hundreds or thousands of kg per month, it would be a big boon, and some of them even develop their own printers.
How come they didn't develop this tech yet? Would be very curious to hear your take on that. Thanks!
I have already a video planned for your mentioned topic "How come they didn't develop this tech yet?" 😀
Large print farms can afford filament extrusion machines to make their own filament from pellets. Then you get cheap AND good print quality.
@@greenboy3d Very exciting! Looking forward to it.
I think the main reason stopping most people is the inherit flow consistency issues that come with pellet exteiders. Pellets aren't the same as filament and there are always going to be some amount of gaps between pellets which causes inconsistencies in flow which are much more difficult to tune for. With most designs I've seen, it takes a good amount of experience and time to be able to produce an acceptable product with pellet extruders
@@Terriblewastaken That seems to be solvable, if nothing else than by increasing the size of the pellet pathway drastically so that the relations error from inconsistent gaps between pellets becomes small and reaches a stable average. This is not really compatible with a moving toolhead, but that's why quantum delta or 2D bedslinger is the right kinematic system for pellet extrusion.
next thing you know you will design a pellet dryer to either integrate into the hopper or have a separate dryer hopper that feeds the main hopper. then you can also add pigment directly into the pellet mix. you know just like a pro industrial extruder
You could "reinforce" the hopper with silica gel that is going to suck up all the moisture in the Hopper keeping pellets dried :)
What would you like to see next? 🙂
actually you could run heater pads on the sides of the hopper walls, do to the distance of the hose and hot air rising out of it , it should create a natural circulation of air including some vacuum from the bottom of the hose or chamber of the extruder@@greenboy3d

What would you like to see next? 🙂
Brilliant. This is the future of 3D printing. Subscribed.
Retraction is why it's not mainstream I almost guarantee, or the lack thereof. The only way I could figure to do it would involve precise tuning to essentially "coast" to the "retraction" point and you just run out of material in the perfect amount instead of sucking it back in a little. The retraction of molten material without a fixed point to pull back from is the issue of course, maybe an air compressor but to create a vacuum instead of pressure? Idk man, this is awesome with a lot of potential!
Retraction in a filament extruder is not caused by the filament retraction itself, but by the underpresure it create. And our atmospheric air pressure then presses against the remaining molten plastic through nozzle hole preventing it for a short time to ooze out until the presure levels balance themselfs
What would you like to see next? 🙂
With Pressure Advance the need for retraction is significantly lower, and with some plastics, retraction almost barely works anyway, PETG for example. Pressure Advance should work the same way with this pellet extruder as it does with a filament extruder. I run 1mm retraction on my direct drive converted Ender 5 Plus, and pressure advance (running Klipper) and it works pretty well with PETG, very well with PLA. I dont print esthetic parts though, only functional stuff where I prioritize strength over looks so run low cooling and high extrusion rates with high temps, neither of which helps with looks :D
This is a nice extruder, looking forward to seeing the end-product, maybe even one in my hand.
But the price of pellets varies a lot. Yes, if you go for the plain plastic pellet types that are used in the plastic molding industry you can get very cheap stuff. But most of the well known filament brands have additives to make the plastics more 3D printing friendly and while they do sell the pellets too, you pay premium prices for this (about 50% of the filament price when I looked around).
So pellet extruders make the most sense on larger printers that are used for high volume production jobs. I still think that using a pellet extruder on a consumer or prosumer style printer is a nice thing to have.
Thank you for your warming words! ❤ But there a couple of things you oversee, because there are not obvious
What would you like to see next? 🙂
True about the material - but the real kicker here is recycling. If you only use Prusament, you could shred your misprints, feed them into your pellet printer and use the stuff instead of throwing it away. I thing that scenario is much more interesting than the pellet printing as such.
Can't wait to see more development on this system. Anyone operating a 3D printing business should be very interested in this system. Well done!
Very cool, look forward to seeing more on this. Thank you.
Thank you for your warming words! ❤

This is epic. You are making 3d printing great again ❤
Thank you for your warming words! ❤
What would you like to see next? 🙂
Seems pretty cool, not much use to me but cool nonetheless, and we know why cheap pellet extruders didn't get made, it's called profit, if everyone could make their own filaments then that loss in profit would be huge
Although while I see this being able to replace a lot of things there are a lot of filaments I don't think this can replicate well, specifically the dual extruded ones, this should be able to mostly do rainbow filaments if you can get the coloured pellets
And thank you for your warming words! ❤
What would you like to see next? 🙂
This is great! I can’t wait to get my hands on one to try upcycling some plastics into new goods!
You did exactly what i wanted to do for ages but havent had the recources yet to actually do it, and i absolutely love what you came up with ❤ very well done mate and with some modifications (im not yet sure how well they would perform and if they would be pracical) that would basically be the go to extruder in my opinion
DU BIST DER HAMMER KRISTIAN!!! Ich danke dir!!! Eine geile Idee nach der anderen haust du hier raus, machst das Leben von vielen Menschen einfacher und hilfst somit der 3D-Druck-Welt sehr Weit voran zu kommen. Du solltest am Ende evtl. noch erwähnen, dass nach einem Umbau nur die E-Steps eingestellt werden müssen, da die Übersetzung anders ist als mit einem Filament. Zu deiner Einschätzung am Ende würde ich sagen - viele Drucker Hersteller produzieren ihr eigenes "teures" Filament, ich denke allein durch diese Tatsache gibt es wenige Ambitionen zu so einem Pellet-Extruder, denn dann würde diese Einnahmequelle für sie verschwinden ;-)
Das sehe ich genauso. Und die meisten Ingenieure o.ä. denken oftmals viel zu kompliziert. Da sind "Hobbybastler" meistens effizienter. Ich bin auch schon sehr gespannt wann der Extruder rauskommt und was er letztendlich kostet.
@@joherberth9230 Lol ich bin gespannt wie viele Ingenieure du kennst .... Eine Firma muss ein sicheres Produkt für Vollidiot liefern die sich nicht verletzen können oder ihren Hamster drin backen, ein Hobbybastler kann eine PLA mouting plate rausbringen obwohl man schon heute weiß, dass es Schrott ist da PLA einfach ein kack Material dafür ist, aber egal wenn man es nach 200h wieder neu druckt und dran bastelt im Hobbybereich spielt das keine Rolle. Hobbybastler nehmen einfach keine Rücksicht auf Bedienerfreundlichkeit, Sicherheit, Dauerlauf etc.

@@greenboy3d sehr gerne, du hast es verdient! :) vielleicht kannst du den Bereich hinter der Schnecke, wo man das Granulat sehen kann / raus holen kann, etwas runder und etwas trichterförmiger gestalten, damit die hinteren „Pellets“ besser vorne raus flutschen können, dann muss man hinten nicht so rum machen mit Werkzeugen.. ;-) ich habe dir bereits Anregungen über deine Website zu kommen lassen.. Zum Beispiel um den Antriebsmotor nach „Extern“ zu verlagern, in dem du eine Biegsame Welle / Biax dazwischen schaltest, zwecks der Kraftübertragung.. :)
As the new president of Argentina Javier Milei says, You can only be successful by manufacturing better quality goods and services at a lower price... and at the same time be a social benefactor.
Super interesting, i will follow this closely
Pretty brilliant design! I like it!
Could this same method be used as a standalone device to make spools of filament? It seems like you’d retain basically all the benefits of using pellets, but you are still able print regular filament, and can use it for multiple printers without modifying all of them
You wouldn't need anything as complex as this to do pellet extrusion for filament. Filament extruders are FAR easier to make as you control the filament diameter by how much you pull the extruded material. Many think you extrude at the final diameter, but you actually extrude at a much larger diameter, and you pull it as it runs through the cooling bath to get down to the target diameter. Some will use gravity to control the diameter thickness, but those systems are much harder to tune to get a consistent filament diameter.
haven't tried it yet, would want me to do it? 😄
@@greenboy3d absolutely, this seems like a great idea
i havent watche the video, but im sure that 3d printing companies are not too happy about this considering they make money off filament! so i doubt youll ever get big support from them. but we the people will support you
What lovely words ❤
If that couldn’t be stopped, they will try to monetize
Amazing idea! So simple and so reasonable! Good job, man! We'll wait for your next video))
I’ve literally been saving my PLA scraps for years hoping someone would do this… can’t wait to finally have it
I'm not sure why you keep talking about printing food. It's a super niche gimmick and won't be the selling point. Have you even considered what would be required to meet food safety standards?
Freedom from higher filament prices and the companies trying to lock you into their ecosystem is a big deal, and makes your concept worthwhile on its own.
The sugar 3D printing is not about eating it, but making insanely cheap "Aesthetic" or low strength parts, that can be spray painted in any desired color 😄
An infinite supply of those breakable prop bottles would be awesome.
Excellent engineering! You've easily earned anothere sub, thank you. Looking forward to getting my own as soon as you are ready.
This is so, so cool I'm going to try and build one as soon as I get my printer up and running again. Being able to use pellets would be so awesome for a bunch of ideas I have

This is very impressive! You clearly did a lot of work. I hope this creates a whole new opportunity in the consumer industry.
I'll do my best :)

@@greenboy3d Perhaps an assembly and first print video? Would be useful for anyone who plans to purchase as well. A demo of using a high end filament like carbon fiber on a fairly large print and comparing the price would be cool.
This could be a game changer, good on you.
This is freaking AWESOME!
Doing my best to improve it further more with the feedback im am gathering through my survey :)
I'ts amazing to see what you've achieved with this project and the potential impact of this is huge! With this mod and a belt printer like the Creality CR-30 a whole new level of continuous 3D print manufacturing can be achieved. Looking forward to seeing future updates and hope you make some good money off this.
Had an similar view of this happening soon to 3d printers while I work with plastic injection and have been producing pellets for long time. I find your minimalistic screw pellet struder very intrincate and yet simple. Am looking forward on your development...this is real engineering at its finest. Open up already a Patreon or something.
Well done, keep it up
Great work! Thank you for sharing! Keep the good work!
Thank you for your kind words :)

Bro keep up the work, this idea is very good.
100k subscribers in 6 months. Quality content, keep it up!
When a smart person commits to a revolutionary project with dedication and passion this is what we get. I've been 3D printing since 2017 and honestly this is the first time ever considering a pellet extruder! Removing the obstacles and optimizing the system while keeping the advantages of the pellet extruder and an accessible price is one heck of an achievement. Wish you all the success!!!
he never mentions the price
Im happy to see youre looking to make this better and better
Thank you! :)

I want to experiment with materials for 3d printing batteries, and this will make it 10x easier. Amazing work.
This looks great. Also great presentation, I will definitely be following your progress!
Thank you! 🙂

@greenboy3d so for me this gives 2 questions, 1. how is the reliability with the various pallets and shredded plastic (I would think that shredded plastic would be less consistent unless super small pieces) and 2. A more step by step guide with specific info on what to get etc with a start to finish build.
But yeah mainly the first thing. For me to start using this, I would need to know how reliable this is. Sure filament is more expensive, but so is energy, failed prints and initial costs. If it's very reliable, this would completely change 3d printing.
very professional vid, smart man, best luck to ya
thanks :)
Brilliant! And thanks for sharing!
Thank you for your warming words! ❤

Don't worry about print quality. People will play with settings to improve it. Just the fact that you got it to work is amazing. You have my respect!
I'm just excited to be able to grind up and recycle failed prints! 😊
Amazing extruder, the gravity fed Hopper really simplifies the design, and is a really great decision to focus on the extruder.
Fantastic ingenuity! Best of luck finishing this project. I would be interested in this for a Bambu p1s.
Nice work!
this looks great man, i cant wait till your done, would love to build one myself. i work in injection molding and have access to TONS of waste resin so this would be amazing to basically print for free!
Awesome. Simply awesome. Keep going!
Thank you for your warming words! ❤

Wirklich gut, mach' weiter so ;-)
This is brilliant! all that's needed then is a shredder to shred waste PET Bottles and failed prints and I can just print with my recycled materials! brilliant! well done
Bravo, fantastische Arbeit!
Danke dir! ❤
Was würdest du gerne als nächstes sehen?
@@greenboy3d als inzwischen vom Bambu AMS Verwöhnter bin ich gespannt wie es irgendwann mal mit dem Materialwechsel aussieht
I like poeple that put their effort to finding solutions. I would not buy expensive pellet extruder as I do not print much but for your extruder I would pay. Great job, keep on ! Looking forward to further progress and other inventions !
This is absolutely fantastic!
The first question I have in mind is how retraction is handled by the system, and the impact it has on print quality so I subscribed to your channel and will look at your other videos.
Thanks also for making the video so educative and describing the typical challenges with pellet extruders. I loved how simple is the solution to swap pellets 😃
Sir, great job.
Never even knew something genius like this existed. Looking forward to further developments!😁
Thank you! 🙂

Great job !
What a wonderfull solution. This i will purchase immediately when it is for sale!
