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

Fits perfectly on the Ender 3 V2, way better than the plastic oem. There wasn’t a notch to hold up your cables so I had to print one before installing. Looks good and works well. You will have to adjust your extrusion after installation.

What a joke. Missing the bed springs and the extruder is not standard. Total waste of money.

This product is bullet proof. Fixed the issues with printing. Easy to install.

I ordered this to immediately upgrade my Ender 3 pr. I was skeptical of this because it was an all in one kit, but the result was great. Im really pleased with the difference in the springs. The bowden tubing is enough for 2 machines. I put the metal extruder feeder on during setup, so I wasnt able to compare print quality, HOWEVER, there was an obvious quality difference in the stock one vs the metal one. Note: Make sure you switch out the couplers and dont mix your hardware up with the stock stuff. It took me a bit to figure out that the couplers were different and an upgrade. Theyre are the ones that gently bite the tubing.

I was having a problem with under extrusion on my ender3 v2 and picked this up and it fixed the problem. This should be on all of their printers.

It was crushing the filament. I swapped it for an old bed leveling spring and it works perfectly

Like many others my CR6-SE extruder didnt last long. I got this as an upgrade and its a direct fit replacement. I will say the instructions leave a lot to be desired and at first I messed up the spring tensioner with another part. However I noticed quickly and swapped them around. It works great and is a huge improvement to the stock extruder.

Everything worked great. However, even though I printed well below the 275 limit (235) and the Bowden still melted.

I’m very new to 3D printing but enjoy tinkering. I bought the Ender 3 bare bones to get more hands on 3D printing. This upgrade kit provided the next step in my 3D printing experience. The bed was more stable as a result and the filament flowed easier. I do recommend using the plethora of YouTube videos to guide in the assembly, unless you prefer to go solo.

Best upgrade you can put on an ender 3 series.
