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

After the plastic one that came with the printer broke, I got these, and it works great. But honestly these should have came standard with the printer, given how often the plastic ones break.

Highly recommend this as an upgrade to your Creality printer.

My Ender 3s have been printing much better since the upgrade. Its also way easier to get the filament feeding into the Bowden tube with the new metal parts. Highly recommended!

i immediately changed my plastic extruder. didnt want failure during printing or deal with a headache. good lenght off bowden tube and spare parts.

Got this kit, complete with all the essential upgrades for my ender 3 pro. Quality parts to improve prints at a decent price. Fairly easy and straight forward to install. (Recommend a tube cutter for the bowden tube, not included) Great customer service as well. Had an issue with my order and the seller took care of it right away, and even followed up afterwards.

The springs are a must have also, I wasnt sure about the bowden tube but it works great

This is a real upgrade. Make sure you also get a glass build surface and ideally the aluminum screws for the bed levelling, and this will make some veey good quality prints.

Repeating another review that explained this perfectly: So. Everything is excellent quality; all aluminum and brass and steel and shiny -- BUT THE SCREW TO HOLD THE ARM ONTO THE EXTRUDER ASSEMBLY IS NOT LONG ENOUGH! The arm is a little bit thicker than the stock plastic one, but the screw supplied is the same length as the original screw that already *BARELY* reached. It needs, like, 1mm more or such. Id be more understanding if this werent Creality-made, but, I mean... they *MADE* the printer, too! Youd think theyd check and/or test things! I have an Ender 5 Plus.

Started experiencing some severe under extrusion on my ender 3 pro. Did every imagineable fix you can find online and it turns out the cheap plastic lever cracked without me noticing. This all metal kit instantly fixed the under extrusion. Every ender 3 owner should get this upgrade to prevent future problems.

Was extremely east to install and worked significantly better than the stock one.
