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

Excellent kit to upgrade printer with metal parts

I have this kit installed on two of my printers. Extruder pieces were well made and came with an easy to follow diagram. Bed leveling springs are strong and keep good tension on the nice aluminum leveling knobs... would definitely buy again.

Just swapped this bad boy in, and so far, this kit works great on my Ender 3 Pro. But here are a few caveats: * The bed springs, even at the tightest setting, are quite a bit longer than the springs that come with the Ender 3 Pro. To avoid scraping your print bed, youll need to either tweak a bunch of settings to offset z, or raise the zeroing switch on the side of your printer. Even with that, I managed to get the printer into some state where it tried to go below the zeroing switch when manually setting Z position, leading to an ugly gouge in my print surface. This may be an issue with the stock springs too, I dont know, but it hadnt happened to me before, anyways. Probably best practice here anyways is to be cautious and dont manually set Z downwards close to zero unless youre in the home position (not directly over the print bed itself). * The extruder uses a larger fitting for the Bowden tube than the fitting that came with the stock extruder. The replacement extruders coupling actually looks to be the same size as the hotends tube coupling instead, which actually is kind of nice, I think. * The extruder doesnt come with a cable clip (unlike the stock plastic extruder). You can just ziptie the power cable to the extra bit of screw from the extruders spring holder screw that sticks out , though.

I would recommend! Just make sure to adjust the ESteps and z-axis sensor after for best performance. (Very important steps)

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.

** Update ** Actually heard back from the seller the next day, they apologized for the mistake and made it right. Took a little while because the kits were out of stock. But received a brand new complete kit and was finally able to install it. Works beautifully. I couldn’t be happier, and now I have a couple spare parts for in the future! Got my kit today, impressed with the previous reviews. Missing a key piece (#2 Extrusion Pin). Without that, this kit is useless.

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

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.

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

So nice To replace original plastic one with a beautiful metal one, same goes for the bed leveling wheels.
