Gwisdom ENDER3 Extruder Upgraded Replacement, Aluminum MK8 Drive Feed 3D Printer Extruders for Creality Ender 3, CR-10, CR-10S, CR-10 S4, CR-10 S5

Everything fits well and works fine. My only complaint is there is not spring pressure adjustment like the stock one had. I may drill the hole out and retap it if I really wanted that feature, but for now it seems to be working fine.This will never break like the stock plastic part did.

Okay "good so far" isn't a great description but to be honest I've only had it on and running for about 20 hours total. Went together great, parts fit, work and look great. Only complaint I have is that instead of having nubs to hold the spring in place, it uses two screws. It works, but it's not as clean-looking. I will say that loading filament through this has been a lot easier than with the stock component on my Ender 3. Not sure if this design is just better, if it's just that this is a new part, or if the Ender 3 component had a flaw.I'll say if you're on the fence, get this.

The counterbore in the arm where the bolt collar should fit is too small, so this won't assemble. The bolt collar is the same size as the original. Some random piece of metal that doesn't show in the parts layout in the ad was probably included to make this assemble, even if not well.I don't know how many miscut parts they have in their bins, but I recommend avoiding this product. Claims of free returns and 24 hour support or not, you shouldn't welcome the chance to need them.

With the help of Youtube, this wasn't too bad to install. It is very durable and for sure will outlast the stock extruder. My only complaint is the tension. Any print that has a lot of retractions shreds my silk pla and fails the print. I'm using my old spring as it has less tension; I may look at the hardware store for something else.

This setup certainly grabs the filament tightly, but sometimes the gear or motor make a CLUNK CLUNK noise every few minutes. The filament doesn't appear to be slipping and there isn't any adjustments possible. Anyone experienced this?UPDATE: I Discovered that this extruder is snapping off my gold 3D Hero filament at the gear. -1 star

I liked pretty much everything about it. It’s nice sturdy seems well built little upgrade for my ender 3. Everything was great. Only down side. Wish would include parts list. Doesn’t really need instructions but simple part list think should go with it. But overall no complaints.

If this feeder skips, you have a clogged nozzle, period. It feeds authoritively and never fails. Quality parts looks like it would last forever. It looks great on the machine too.

I just used the tension arm and reused my original body. Theres no spring tension adjustment on the new body.

this was supposed to include the bracket.... no bracket... cannot use the item

I couldn't install the product into the printer because there were missing parts. Really disappointed!
