Creality Official Upgrade Extruder, MK8 Extruder Alloy Block Bowden Extruder 1.75mm Filament for Ender 3 Series, Ender 5/5 Plus/Pro, CR-10 Series 3D Printer

This is a direct match to replace the plastic stock extruder

The stock extruder assembly on the ender will fail. This replacement never will. Easy to assemble- 5 min to swap it out. Great product.

It took me a little while to figure out that the m4 screw and the m3 rivet nut was on purpose so you can back off the m4 screw to adjust the spring tension. Product works just fine on my ender 5 plus.

Installed onto an Ender 3 Pro and have to say the difference on my prints is night and day. No more under extrusion problems and actually feeding new filament into this is so much easier than the stock one it came with. No more fiddling with the end of the filament trying to find the hole that goes into the bowden tube after the gear. Slides right through and down the tube. Paired this with some capricorn bowden tubing which also makes a difference compared to the white stock tubing. So far well worth the money.

The extruder upgrade works fine on a CR-6 SE and is worthwhile upgrade. I wore out the brass gear in the stock extruder and taking the stock extruder apart to service is a huge pain. It is also difficult to re assemble and is made of cheap plastic. The M3 X 18 SHCS screw in the kit is a little short but there is a longer M3 X 18 SHCS screw on the CR-6 SE stock extruder that you can trim to have a screw the right length. The M3 X 18 SHCS screw in the kit worked for me, but I was careful and did not over tighten. The seller in the Q&A says that this will not fit on a CR-6 SE for some reason. This upgrade works just fine.

description says CR-10s series but should have added NOT Pro

Is this the best extruder on the market? Nope. The big brands (bondtech, e3d, ldo, etc.) are all going to push filament more reliably. This one only has a single drive gear, so its never going to power through partial clogs like those can. That said, its dirt cheap comparatively, so if youre just looking for something that can apply more force than the stock plastic extruder creality includes on some of their printers, itll give you a nice improvement.

I was glad to find this product after my factory installed failed after a month.

Product is a lot better quality than the plastic factory options (mine had a groove worn in from friction feeding through PLA). The instructions for the product are not good, as they are only a picture but it was not hard to grasp. Only reason I knocked down 1 star is due to the method for the extruder spring tension adjustment. It’s the head in screw which is small enough that it still sits inside the spring. Could remedy with a small washer. Otherwise everything has been great, and even at the lowest level, the upgraded spring was a boost as it helped the tension.

This should be on the factory ender printer. This is worth every penny as it made an immediate difference in the way the filament controls. Well worth it.
