This is the first upgrade that everyone should do with their compatible Ender 3D printer. That plastic one that comes with it will fail and it will ruin one of your prints. This fixes that issue as long as you keep the nut tight.

Replaced the stock extruder on my CR-6 SE as lots of people complain it wears down too easily/quickly. This was pretty easy to install (definitely easier than re-assembling the stock one) and gives me a bit of peace of mind.

It comes with no instructions Which is odd but like everything in the world there’s a YouTube for that! What I wasn’t sure about was the fact you don’t use your tube “fitting” on the extruder you snap a little plastic piece in there and shove your tube in and install the little lock...to my surprise it grips that tube perfectly!!! On to the extruder itself, it’s very well made, easy to install and looks fantastic. Also as I was told it does in fact reduce stringing to a noticeable degree! Worth the money!

Was having nothing but problems with the stock extruder on my Ender 5, and this part immediately resolved the issues. Best purchase I have made for the printer.

Great product, really improve your prints. Best 3D shop in Canada

I was having inconsistent lines on my first layer as well as random missing lines, bad adhesion. I replaced all "other" parts in the process but it wasn't until I replaced the Bowden extruder that my problems vanished. The original part looks brand new but it obviously has an issue.

I was hesitant to purchase without a spring adjuster but after installing my extruding issues were fixed. I also realized that installation of washers on the spring pin will create a incremental tightening of the spring so it is adjustable after all.

I’ve been using this extruded since I got it. No more problems with skipping like the old one. It’s clean corners and smooth surface is a bonus. It was also very easy to replace.
