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

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.

Perfect for my Ender 3 Pro v2 easy to use and is a great fit. Been printing with it for a while and it works perfect. No issues with a self leveling bed.

Came with everything you need great fitment works excellent and must have upgrade

Only used some parts rest are saved for sparesAll springs the same size the one by bed heater cables needs to be shorter I just used one of the original weaker longer springs

Out with the old, in with the new. Good product! Everything works now

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.

Fit perfect, installation was very easy.

Good quality and the tubing has a smaller inner diameter than the ptfe tubing. Seems to help with filament guidance.
