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

Not worth it missing the threads to screw in tube holder. I cut the tube before I notes it was missing the threads.

I did a bit of research on buying these products and there are a few out there with worse reviews and even higher prices somehow. So I tried this one and everything worked. All the reviews were pretty much spot on. You can tell F1rst Layer have used a lot of Creality printers because they can identify most of the parts one would need to compensate for the cost saving deciwsions Creality made when manufacturing their printers. This is probably the best bang for your buck upgrade kit on Amazon.

good quality

Two issues I faced right out of the blocks, the hole for the screw (on the extruder arm) was not threaded, that step was forgotten and not noticed by inspectors. Ill have to tap threads into it myself. I would have simply sent the kit back to Amazon, but I had already cut and used some of the Capricorn hose.

Parts arrived quickly. The all metal extruder seems well built and installed easily. There were no instructions provided but I was able to find without issue via google. I installed bed springs as well but honestly not sure they were any different then the ones I already had? They seemed to be the same color and spring rate as to what I had. All items were installed on my Ender 5 Plus without issue.

Appears good quality but decided to go to with dual gear driven one instead. Not worth sending back will probably use some of the parts for something

The extruder is not threaded for the fitting. Product image shows fitting on the extruder.

Would recommend

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.

This product is really well built and has worked perfectly for me
