Creality Upgraded MK-8 Metal Feeder Extruder Frame Aluminum Gray Bowden Extruder Drive for Creality Ender 3/3 Pro/3V2/5/5 Plus, CR-10 Series, CR -10S/20/20 Pro 3D Printer

It is as it says. install is not hard. does not really effect my print quality any, for good or ill.

This came as a bonus for purchasing the printer. Was easy to put on, and works with no problems.

Works great for me, thank you,

In the photo Im showing the plastic arm isnt as thick, but the screw they include is the same length making it only grab one thread or so. Very very easy to strip. Emailed and they dont have longer ones. Ill have to find a longer thread someplace else.

if youre having extruder issues try this before replacing the head i had prroblems with my cr10 smart and this fixed most of those problems deff worth a try printing way cleaner now. the stock setup isnt going to cut it you can tighten it but the way they have it setup the spring doesnt always backout when you loosen it i noticed so basically have to take it apart to l get the spring to backoff and its a pain to put together just make life easier and try this before doing anything else oh and get the upgraded bowen tube its blue cant recall the name tho sorry

Easy to install, dont know if there a improvement because I installed in my new printer while assembling

Shipped quickly. I have the ender 3v2 but have to say this extruder Im much more happy with. It matches the machine and it is SO much easier to load the filament into. The rest of the parts I will eventually need.

Exactly the extruder upgrade your looking for. Very reliable

Made the process noticably easier.

I ordered two of these about two weeks apart. The first one was complete and had the correct hardware. The second one is junk and the screws included with it are the wrong size. It is like they were made by two totally different manufacturers.
