3D Printer Kit with Aluminum Ender 3 Extruder Upgraded, Compression Die Springs for Bed Leveling, Metal Hand Twist Leveling Nut Suit for Ender 3 Pro/5/5 Pro, CR-10 Series/10V2/20/20 Pro

I had to use the old springs. The new ones are to long. I may need to trim to fit.

Just received it today, and it is a significant improvement from what I was working with, the original extruder that came with my ender 3 pro was made of plastic and over the course of 6 months of printing it cracked and no longer extruded properly. This metal extruder is a simple drop in replacement and the build quality is supreme. Now for the bed knobs and the springs. The bed knobs are beautiful and high quality. The springs are a bit longer than the original but they are super strong and I feel like they will last a while. I had to readjust my z end stop to be a little higher, partially because I have the glass bed upgrade but other than that I would definitely recommend this kit to anyone. I will update this review if I come across any significant issues in the future!

Amazon has a serious counterfeit product problem. After purchasing another of these kits its clear this is a counterfeit kit I received this time from this seller. Who knows if Amazon just grabs knockoffs off the shelf vs legit products or if sellers know theyre selling counterfeit products but this time it appears to be real. Hardware is tarnished and cheapish, fitment is sloppy, having the two side by side makes the knock off obvious. May the odds be ever in your favor.

Works great, this is a good upgrade when the plastic extruder arm finally breaks. The springs not that useful with buildtek, but if you have a heavier bed with glass they might be useful

Quick and easy to swap out the bed springs and leveling knobs. However, I was missing the feeder replacement that sits on one of the motors and the threads on one of the parts wasnt machined properly so I was unable to screw the movable arm for the feeder assembly in place. Need to contact creality or the seller for a replacement.

Dropped one star for the fact that the springs are too long for the bed of my Ender 3 V2, the kit however is still fantastic value. The red wheels and the metal extruded are both big upgrades over the standard plastic ones and both are simple to install. Recommended!

Springs do not work with ender 3 pro.. very disappointed that after getting it all set up the springs won’t work unless the switch is moved

I wish I could review the entire kit but the only usable item for me are the red tensioning wheels. Wheels: great Springs for wheels: way too long to be useful anywhere. Extruder: worthless. I’ve had to use stock screws, specialty parts and it still won’t feed filament. Update May 11: despite best efforts, none of the parts were usable for my printer. The wheels would cause the bed to raise over longer prints, failing multiple larger pieces, extruder assembly never did function properly. I’m keeping them as spares just in case a third machine will work better, but as of right now, not the parts for me.

This “upgrade” came up as being a deal and discounted when I purchased my Ender 3 V2. First off the springs included with this kit are too long. It makes the bed too high. The extruded upgrade was well made but never seemed to do anything better than the original and in fact never worked quite right on my printer. The only thing I really used in this kit was the metal leveling knobs. That’s the only reason I’m giving this 2 stars. The rest was just a waste of money for me.

These are great springs, still have to use washers on the front to compensate for it being a cantilever tipping a bit forward, how ever these keep the bed level longer. The extruder rocks, make sure you have the ability to replace the Bowden tube and tube nuts when replacing this extruder. The all metal wheel nuts are awesome and hold in place better than the plastic oe ones.
