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

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!

Went together smoothly love Capricorn tubing and the stiffer bed springs. The metal extruder parts make the machine look more solid I hate seeing plastic on important functioning parts

nice kit, include a lot update at low price. you should have one

There is NO WAY to attach your bowden pneumatic fitting to this. I of course assumed something so basic would work and only found out at the end of the install that this product is fatally flawed. Worse yet, the seller KNOWS this but keeps selling it anyway. How this gets to be an Amazon Choice is beyond me. Stay away.

Overall good quality parts. Only issue was one of the threads stripped really easily and can no longer be removed. Now Ill have to replace the entire module if I need to change anything.

Super easy install. The parts are good quality. The instructions are just an exploded diagram so find a good YouTube video. It comes with some spare parts. Overall it is pretty great.

Good quality

The previous shipment of these upgrade kits had a different design, but this amazing company helped me get a new one with the threads. I have had nothing but good interactions with F1rst Layer and they are the ones I come to to buy printer parts.

My plastic extruder broke after 100 hours. I can tell this aluminium extruder will certainly stand up much longer having used it for 50 hours of prints already. Its always nice to change up the Capricorn tubing you are using from time to time just to keep things running smoothly as well. The springs and fittings worked as well. I am satisfied with the results so far.

Awesome upgrade kit great price for it all..the one oy bad thing about it is lack of instructions.
