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

The kit arrived and all appeared well. When I went to install the upgraded extruder I found that the main base piece that mounts on the motor had a major flaw. The point where the pneumatic fitting goes was not correct. Neither of the replacement pneumatic fittings included fit. One was too small and the other too large. I Then removed the original pneumatic fitting from the Ender printer, it had the same smaller diameter threads and was too small to fit. Upon closer examination, I discovered that the hole on the upgraded extruder part was not even threaded. I could not even start to replace the parts because of this flaw. I emailed the company directly explaining the problem and asking for a replacement part. After two days of not hearing back, I returned the kit to Amazon. I am surprised that a part like this was not discovered to be flawed. Also, the customer service after the fact was nonexistent. There are many metal upgrade kits for the Ender 3D printers. I will now be searching for another. There are many good reviews for this kit, but if their quality control allows even one defective part through its probably not worth your time. I am now delayed by a couple more weeks before Ill have my printer up and running.

Very easy to install, works 100x better then the original part.

Great product. Easy to install.

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.

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.

This is a great upgrade to an Ender 3. The package arrived quickly and everything was as described. It was easy to add on the parts and so far my prints have been slightly improved. My old stock extruder was starting to wear and was probably close to breaking. This aluminum extruder will definitely hold up a lot longer. The upgraded bed springs and the capricorn tubing were also a nice addition. The springs are a lot stiffer and I dont have to level my bed as often as I used to. The capricorn tubing is definitely a must have and I wish I would have upgraded to it sooner.

The Capricorn tubing was horribley fake. The tolerance was so bad nothing fit through it and looking at the cross section middle hole was so far off from center. it looked like pasta. Lol. I’m sure it was not even Teflon based. Watch out for this cra pp.

Great upgrade for Ender-3 Every single part of this upgrade has made noticeable improvements to my Ender-3. The extruder was the only part I had to youtube how to install and there a plenty of videos explaining how to do it. It was an easy install. The springs look miles sturdier than the ones came with my printer, same too with the fittings. I would highly recommend this upgrade to anyone with an Ender-3 printer.

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??

Not impressed with Capricorn tube. went back to the white that came with my printer. Next day delivery took 3 days. Want a better review, make some changes.
