Upgrade Ender 3 Extruder, Ender 3 V2 Upgrades Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Creality Ender 3 Pro/Ender 5 Pro/Ender 5 Plus/CR-10 Series 3D Printer

This is a great little kit, don't get me wrong - it is great value and adds some small nice improvements but some of the reviews are outright misleading. No, this won’t increase your print quality basically at all Nor does it allow you to increase print speed in any way. The amount of factors that contribute to the end product of a print are many and tiny tweaks here and there can be either imperceptible or be the difference of printing a blob of ugly plastic spaghetti. Good calibration and tuning of your settings, steppers, flow rate, temps, retractions, leveling, and combing settings are going to have infinitely more of an impact on your print quality and speed than most physical upgrades and this product is no exception. If you want more out of your printer, look into those things first! Even if you have a 5 thousand dollar printer, it’s nothing without those tweaks! BUT That doesn’t mean it is a waste, far from it. I like this little kit and it’s a nice humble addition to my lovely soldier that is my Ender 3 Pro. My stock extruder clamp actually managed to snap one day after several months of use, but with this version I certainly won’t have that issue again! It fit really well and so long as you assemble it correctly, the tolerances and accuracy was excellent. Having tried one of the red “off brand” versions just prior, that thing sucked. This one has actual precision in its creation, I was actually amazed because I wasn’t really expecting much of a real difference either. I could go off about just how crappy the red one I got prior, but I digress. The Capricorn tubing is nice and it is better than the stock PTFE tubing, but it is also not magic either. The tolerances and precision of the tubing IS better, I checked. For most standard print materials like PLA and PETG, there is exactly zero difference using this, despite being superior. HOWEVER, with other filaments and special use cases, there IS a difference. Some TPUs and filaments that happen to run particularly hot (like, hot hot) you will actually find there is benefit to this tubing. I will give credit where credit is due there, I just don’t want people getting the wrong idea that these things just magically make better prints - it just isn’t that simple most of the time. The addition of the bed springs is, I mean, sure why not? I hope I don’t really need to explain that this isn’t going to be magic either, but they seem very well made and I imagine will hold their leveling for a while. At the end of the day - Yes it is a solid upgrade IF you have already given your printer the proper love and attention so it can do it’s best already. The added durability of parts and flexibility for options, coupled with a nice style - I do certainly recommend it. Just make sure you actually understand it before falling into the placebo of magically better prints like some reviews seem to have done. That isn’t anecdotal evidence that it doesn’t improve prints - It is just straight up not really how a 3D printer works. But if you want a lil upgrade for your Ender 3, by all means this is a good choice.

Everything came packed in some transparent bags. The extruder is very easy to assemble, it came with instructions but they are not even necessary. Very satisfied with the product. You should take on account that this is not going to improve your print quality. This upgrade is intended to increse extrusion performance. The original extruder, plastic, can broke on time and it is more prone to skip. The metal one is intended to work for more time without issues. Also, I would highly recommend to attach an stress relief device before the extruder. It will reduce friction on the input hole and avoid hole wear. It is metal, yes, but 300m of PLA can erode that metal and kill your extruder. Edit: The Capricorn really is a mandatory upgrade. It will increase your print quality in another level. Currently, I changed from 4mm retract to 2mm and I'm thinking about setting it to 1mm. There is no stringing at all and the fit is just exact. One important point, it is so thigh I'm having trouble with filament change. Overall, I feels like having a direct extruder.

Worked perfect for my Anycubic Kobra. I dislike their OEM extruders. Yes, I had to reverse polarity for the motor, but it was worth it. Feeds TPU better than the OEM, good tension and I haven't had any issues so far (about 20hrs of random prints with PLA and TPU). As expected, had to change the E-Steps, for the Kobra it's about 98.5 if that matters. I'll probably buy another for my Chiron too. After assembling the new parts, I used the OEM extruder-gear and placed it back on top of the motor shaft to be able to manually twist feed/remove filament while depressing the tension handle. You could easily print your own wheel to assist, but since I had it and it's metal and compact, might as well utilize it.

This metal extruder made for a nice upgrade on my Ender 3 Pro. The plastic factory extruder cracked and this kit includes a much higher quality metal extruder. Instructions are included, but there may be a tiny bit of variation depending on your printer. My packaging was missing the screws that hold the filament tension spring in place. With the old plastic extruder in hand I was able to salvage some pieces to make everything fit. The Capricorn bowden tubing included in the packaging works great so far too. I'm familiar with using Capricorn tubing and this seems legitimate and has held up throughout a week of constant printing. There should be enough Capricorn tubing for 2 uses, but it varies depending on your setup. The only thing included I did not use were the bed springs. I already have silicone bed mount spacers that work well and didn't want to mess with the great results they were providing. For the $15 price, there is a lot of value here! The metal extruder is quite the upgrade and is much easier to load filament.

So, I saw the writing on the wall for my old plastic extruder; no cracks in the body of it, but the odd tube holder attachments just snapped the other day (I tended to place my thumb on them when changing filament). I did a little research, since I knew I had an Ender 3 Pro with a pressed in hobbed bolt on my extruder motor (from what I've seen, this only accounts for a couple years of production for the model, so check for yourselves if you have them). And since I really didn't want to replace my stepper motor, I thought this upgrade should work with what I had, better than most other non OEM setups. I was correct with my assumption. Assembly wasn't bad, took me about 20 minutes following the exploded diagram sent with the package. I really can't say it's printing that much better than the stock item, but I can see a difference in ease of loading filament for sure. With all that said, I thought it was a great inexpensive add-on to my printer. I got the added capricorn tubing and springs as spares, since I already had them on my setup. (worthwhile backup items)

The ptfe tube is original from Capricorn PTFE. Excellent quality. Was worth the price

You can expect the one that came with your ender 3 to break, they always seem to. This is much better quality and has been going strong.

Es bueno, pero tuve que encontrar una solución extraña que involucre mi propio hardware para montarlo en mi ender 3 pro porque tengo la extrusora de accionamiento directo

Très bon produit. Ne pas trop tendre le ressort de l'extrudeur par contre, car après la roulette déforme le filament et il passe moins bien dans le tuyau ptfe. Pour les ressort que du bonheur.

I bought this because my stock extruder broke and wasn’t pulling enough filament in. The installation was very simple. I had an issue with my motor since it’s the older version, and had to cut the little gear off. The shaft was also shorter but instead of buying a new shaft, you can just put the new gear upside down. It works great! Also, if you have the older motor, you will have to grind down a flat surface for the set screws to sit in. The tube was a very easy install. The springs are way stiffer than the stock ones. They are also flat on the ends and have the bed sit on them perfectly even. Overall, this is a MUST BUY. Even if your extruder isn’t broken, get this one because it preforms so much better!
