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

The springs alone increase the quality of life with your printer. I rarely have to keep leveling the bed (even with a BLTouch). Having an all metal extruder is also a must have.

Springs are too short for the bed. The gear for the extruder motor on the Ender 3 can’t be removed. Save your money for a CR or BL touch and just buy the all metal extruder parts.

It lasted only a short time before the threads wore out where the screw holds the wheel in the handle.. had to put the old handle back on temporarily.. I know the one I got wasn’t worth …. Maybe just this item .. but it broke …

The metal wheels are designed so the edges of the wheel are further up then extruded center pin. So the edges scrape and its difficult to spin. Terrible design. But I put all the other things on it already so I wont bother taking the rest apart to return it

Bought it a month ago and worked great, but was disappointed when I noticed extrusion problems after a long (25 hour) print using glow-in-the-dark filament. I know that type of filament is abrasive, but that is the whole point of buying an all-metal extruder assembly. Took apart the extruder to clean it only to find the hole where the filament enters the extruder had worn out completely. Fortunately it is inexpensive to replace, but was disappointed that it didnt last longer. The replacement bed springs and adjustment knobs are working as expected.

Legit deal. Legit parts. Everything is exactly as described.

Everything was fine except one of the leveling wheels would go on because of bad threads. Springs are great, extruder seems to be of great quality. Not too worried about the wheel, as it was my least needed thing of the package, but still a little disappointing. Other than that Im very satisfied

Parts were well made, and fit and performed well

While much of the installation is obvious, a few items were not and documentation was lacking. I could not determine how to install the new drive gear properly. The bed leveler wheels need deeper offsets to be most useful.

Everything seems to be quality and fits well only issue was the springs were a little too long for my ender 3 pro so I just raised the z spot a little and after a little trial and error got the bed leveled.
