Creality Original Metal Extruder Drive Feeder Upgrade for Ender 3 Pro / V2 / 5/5 Plus/Pro, CR-10 Series, CR-10S, CR 20/20 Pro 3D Printer Accessories Parts CR10 CR7 CR10S MK8 Kit

Does not sit correctly on the extruder-motor plate, thus, filament does not line up correctly when coming up through bottom of extruder, to the little hole that leads to the Bowden tube. No way to see in to guide it correctly. No instructions came with it Not sure which it DOES fit, but definitely not Ender 5 plus

quick release claw breaks easily

This does seem to be an official Creality branded kit that Im sure will fit any of the advertised units. It matches up perfectly with my CR-10 v2. Im not convinced about the quick-release claw. First, there doesnt seem to be any replacements available and no extras are included. This will certainly wear out over time, and, functionally, it is still a push-pull insertion thing so I dont really see why it would be any better than the standard couplers. Also, since this isnt threaded, you cant even go back to the old ones. We certainly need some sort of improvement over the current PTFE tube couplers, but Im not sure this is it. A big one for me is the toothed gear. I bought some generic replacements and they only had one grub screw. This one has the proper two. That is almost reason enough to go with this kit over some other. Priced well, official Creality, recommended.

This has an updated bowden tube output. No threads for a normal pneumatic coupler. Seems to work great so far.

Easy to install, did not affect print quality. No affect on print accuracy. But looks nice. However l was unable to use the extruder knob, due to the shaft being to short, see picture. Also filament now slips with a distinctive click. I do not recommend.

Instructions would have been nice. But works great after original plastic one broke.

This is a decent upgrade to a stock extruder. THIS IS NOT A DUAL GEAR EXTRUDER. But I knew that when I got it. If youre still using the stock plastic extruder, it will break someday, so I would recommend having one of these for when that day happens.

I ordered the kit. Came as pictured, no way to attach Bowden tube holder. Ordered replacement. SAME THING

Better than the plastic ones that come on it. Put them on all three of my printers now.

Great upgrade to the plastic version, it just makes everything better.
