Authentic Creality Aluminum Extruder Upgrade Kit for All Creality Printers with Capricorn PTFE Teflon Tubing, Upgraded Premium Metal Bed Springs, PC4-M10 Pneumatic Fittings and Two Blue Collet Clips

Great item at a great price, was only looking for the Capricorn tube but this kit came with so much more for only a few Bucks more. Fast shipping too.

I install this on June 3 first print came out perfect. Every other print since then total about 45 Prints I’ve came out messed up filament stops feeding halfway through then starts back up then stops again. I have changed out the gear I have changed out the bearing I have added tension I’ve taken away tension I have replaced it with different springs will not work put the old one the original back on printer runs perfectly fine.

This is an excellent upgrade to the Ender 3, I highly recommend. The quality control issues of previous units has been fixed, and this one all the parts fit together perfectly. The seller has been amazing in communicating and fixing these issues. They have also included easy to follow instructions now, which makes installation much easier.

These upgraded springs are keeping my bed much more level and are a massive upgrade over the stock springs. I dont have to level my bed after every print now. The blue clips included are great and the fittings have teeth inside which grip the PTFE much better. The extruder is working well too and is much easier to feed filament into as opposed to my old plastic one. Capricorn is the best PTFE there is and anyone with a bowden style printer should buy it.

This is a great upgrade kit with many of the recommended parts to eliminate the factory flaws!

After having been using these upgrades on my Ender 3-v2 for the last several months, I can happily say they are definitely worth the less than $20 price tag. Initially I only installed the Capricorn PTFE tube and new fittings as these are a major need for most printers. If I could take half a star off, I would, simply because this kit does not include a flush cut tool for the PTFE tube. Having as flat (flush) of a cut as you can get on your PTFE tube is absolutely necessary to prevent any filament leakage on the hot end. To get around this, you either have to order a tool and additional Capricorn tube, print a tube holder and hope you keep it from sliding when you cut the tube or come up with a different method. I tried a couple of the printed tools and my success was not that great. So I went the alternate method and loaded my Capricorn tube into one of the new fittings and used the metal edge of the fitting as a guide to cut the tube perfectly. I waited a couple of months before swapping out the bed springs. I wanted to make sure I had a great understanding of how the printer worked and why you benefited from changing springs. After having to relevel the bed with the factory springs a couple of times, I swapped in the orange stiffer springs and have only had to make minor tweaks based on filament changes. The last part I changed out was the metal extruder. I did wait until the factory plastic extruder broke. You know it happens because you get a continuous over or under extrusion issue. The installation of the new metal extruder was very straight forward and took me less than 10 minutes; your time may vary depending on how mechanically inclined you are. MAKE SURE YOU DO NOT MIX UP THE TENSION SPRING FOR THE EXTRUDER WITH ANY OTHER SPRINGS YOU MAY HAVE. They look nearly identical to bed springs and bed springs are about 4mm too long for the extruder and force the toothed gear to chew up your filament and cause prints to fail. Overall, I give this upgrade kit a 4.5 rating and highly suggest it. Is it necessary to wait to install everything? Not really, but learning more about your printer in its absolute factory state will help with troubleshooting in the long run. @Creality, if you read these, please include a good flush cut tool for the Capricorn tubing!

I already upgraded my Ender 3 with a bltouch a couple of months ago so i already knew how vital they are. Im using this kit on my ender 3 pro and its the first time iv used Capricorn. It makes SUCH a huge difference, not only in because I can now print more exotic filaments but also in how intrinsically slippy it is compared to normal bowden tubing. The upgraded springs in this bundle are also superior because they increase the tension and stability of the bed due to being much sturdier springs. The couplings included are also much better than the stock ones that came with both of my printers because they have metal teeth inside that grip the ptfe. I will definitely be buying off this company again. Why aren’t creality selling these parts stock with their printers??

Upgraded tubing and filament feeder from the plastic one that comes with Ender 3 Pro since I was having trouble printing. Once the upgrade was done the upgrade works well and the machine is printing.

Defective. No thread on extruder. Springs are too long bed cant level. Bad product. Stay away.

This is an amazing kit and a must have upgrade from the stock extruder. My original plastic extruder eroded from the filament passing through. This caused the filament to jam up and led to severe under extrusion. This upgrade completely fixed this and I have great prints again. I couldnt recommend this enough to every Ender 3 owner.
