ComgrowCreality Capricorn Bowden Tubing 1.75mm 1M All Metal Ender 3 V2 Extruder Pneumatic Couplers Bed-Level Springs for Ender 3/Ender 3 V2/ Ender 3 Pro/Ender 5 Pro 3D Printer

This kit is amazing value for the price, and seriously upgrades all the biggest flaws of the Ender 3 out of the box. I bought this and the PEI sheet for my Ender 3 printers, and have never looked back. Save yourself tons of time, troubleshooting and headache! Buy this kit before you print!

My bowden tube clip broke on my Mini Delta filament feed assembly and that is a non-standard part. I replaced the entire drive gear assembly with this part and now my printer works again! One thing to note...the tension spring that presses the drive gear against the filament is a bit stronger than the original...but that can be adjusted on this replacement part since it has an adjustment screw! Overall, very satisfied with my purchase and worth the money!

What can I say to convince you to get this? Let me start with what I am running. I have an ender 3 v2 with a hictop pei flex bed plate. Updated bed springs, and that’s really all. For the time of owning this printer I’ve upgraded a few things but never the extruder component. Didn’t think it was a necessity, I mean I was getting prints right? Would something so simple make that much of a difference? Well one day trying to print and my filament was not being extruded correctly. My e-steps, I thought we’re on point but i increased them to see if that would fix it. No amount of increase helped, it was inconsistent, spotty, crappy, and down right disgusting. I took apart the plastic extruder to find the arm had cracked along the gear housing, just like so many people have happen before. I looked at dual gear extruders, not knowing if it would be that important for what I print and decided to get this one. Immediately after instal I checked my e-steps and once I returned it to where it was before, 97.2, it was extruding perfectly. The upgrade all metal extruder almost seemed to be too stiff, I was worried that it would chew the filament because of how tight it seemed. Leveled the bed again, ran the test prints to ensure the leveling was on point. The filament is running so constantly, I haven’t had and issues with what I was before. So printed a Pokémon, fidget spinner, and a few other things. All came out perfect. I was getting results I hadn’t gotten before. I know they say that this won’t really improve print quality but I argue that 100 percent. Why wouldn’t creality include this off the factory floor? It’s such a blessing to have my worries about prints failing lessened. My prints have such a smooth finish it’s amazing this is still the same printer. I’m not getting those whispy filament pieces from travel, I’m able to increase the printing speed, and I’m not running the temps as hot as I was before. Yes I’m sure you need to make sure your slicer settings are tuned in. The thing is, my slicer settings were tuned when I was running the old extruder. My setting were tuned to make up for the unknown issues of the plastic extruder. So in short, GET THIS, get it as soon as possible, this should one of the first things to upgrade.

its the same thing it came with. it heats up fast and stays hot.

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 allNor 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!BUTThat 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.
