Creality Upgrade Ender 3 Extruder, Ender 3 V2 Upgrades Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Ender 3 Pro/Ender 5 Pro/Ender 5 Plus/CR-10 Series 3D Printer

Great upgrade, had held up well for several months now of frequent use. Not sure if this is truly OEM Creality parts as there have been several versions of these parts, but even if theyre not, the quality is good enough that it doesnt matter.

Great value upgrade kit! The Ender 3 should have come out of the box with these parts. I love the sturdy feel and build of this metal filament feeder. The Capricorn tube replacement was great. The old one was actually pretty worn out and this will reduce friction on filament. The bed springs are sturdy and stiff and will keep for a long time. These are all some essential upgrade parts for the Ender 3. Glad I bought it.

I ordered this kit as soon as I purchased my ender 3 v2 on a recommendation. I can’t speak to the quality of the quality of stock parts but the kit for springs and extruded, and tube has been awesome. I haven’t had any issues yet. Make sure to take your time and look at the review images if something is confusing. The “instructions”don’t help too much.

If you have a Ender 3 pro. This is a must for your printer. The print quality went way up.My prints are a lot smoother.Three thumbs up.

The springs were hard to install kind of. I did a print with them and it went good then I trided to print another thing and it did not work at all I releveld the bed twice and it was the same then I changed back to the stock springs and it was fine. The metal extruder was excelent easy to install and the PTFE tube was pretty wasy to install on the Ender 3.

Dont wait for the original plastic extruder on your Ender 3 to crack. Get a metal one. Thats some of the first advice you will get on any 3D printing forum, That and to get Capricorn tubing. The yellow bed springs do seem to be holding their position better than the originals. There was about twice as much tubing as you need in this kit for an Ender 3. Its a good idea to keep it as short as you can make it while still flowing smoothly into the hot end at its furthest extension. I was even able to successfully print using TPU after installing this upgrade, even though everyone thinks you need a direct drive print head.

Has the dark blue Capricorn XS tubing with tight tolerances and high temperature rating. Really good quality pneumatic couplings with metal teeth and a nice snap actuation. The extruder is properly dimensioned so that it doesnt bind when the pivot screw is tightened. The tensioning spring comes with a little sleeve that allows you to adjust the spring tension with a screw. The die springs are a worthwhile upgrade, making bed levelling easier and more stable.

This is another great creality product for the ender 3 work horse

used it to replace the factory one for a ender 5 and was much better then the factory one which was plastic.

The M3*18 screw included to secure the swing arm to the extruder stepper motor is 2mm too short due to the increased thickness of the arm. Sure, its sturdier, but if the screw cannot attach it to the stepper, its useless. If the kit included an M3-0.5*20 screw, wed be in business. The attached image shows the length of the screw protruding from the bottom of the arm when the head of the screw is flush with the top of the arm and sleeve bearing. In the picture, original plastic arm on the left, kit aluminum arm on the right. Its just not enough to grip the threads inside the top of the stepper. Extremely poor engineering.
