YOOPAI Metal Leveling Nuts and Springs Nozzles Heatbed Silicone Leveling Column Mounts Hand Twist Upgraded Set for Ender 3/3 V2/Ender 3 Neo/Ender 3 S1 Pro/Ender 5 Plus/CR 10 Series 3D Printer (4Pcs)

I think these are a perfect fit for my Ender 3 max neo. It really fits the red color scheme. They are super easy to install and work great. The extra nozzles are just a bonus. The price is great. If I have one criticism it is that I would like them to say up and down with arrows on which way to turn them. I may be the only one but I always spin the wrong way first. Im using the silicone feet on one printer and the springs on another.

I am currently (always, LOL) in the process of rebuilding one of my Ender 3s, so I figured this kit might be a good place to get a few extra pieces. For the price, it seems to be a pretty good deal. The leveling wheels are very solidly constructed, all metal, and are much nicer than the originals that the printer came with. They also have a nice texture on the edges to make them easy to grip and turn (though it would be even nicer if they also had up/down labeling on them). The upgraded springs that come with this kit also appear to be well made and a bit stiffer than the original Ender 3 spring (which is a good thing). Personally, I will probably be using the 4 included silicone spacers rather than the springs, as I find they tend to do better at damping Y-axis vibrations/oscillations than the springs do and yield better print quality with less salmon skinning in Y. The silicone spacers seem well made and one of them is shorter than the others, as it should be, to allow room for the heat beds plastic strain relief. The 4 included nozzles seem fine but unremarkable, but it never hurts to have a few extra nozzles! My only other observation would be with regards to these springs being slightly longer than the originals and their recommendation that you may need to trim them. Rather than trying to trim them, at least for an Ender, it is MUCH easier to just readjust your Z end-stop switch up by a few millimeters. Overall, this is a nice little upgrade kit.

lost one of my knobs to my sunlu printer. Got these and the fit right up. Really like the color also.

These fit my ender 3s perfectly. Even gives you a choice to try the harder springs or the silicone spacers. I personally perfer the silicone spacers. Good price for everything thats includes.

These are great. The springs that came stock on my Ender 5 Pro had worn out a bit, and the ones on my Neptune X were pathetic to begin with. I replaced them both with these. I like the size of the tuning handle better and that they are metal too. A very worthy upgrade!!

Got these for the silicone spacers to make life easier when leveling our Ender 3 Max Neo, and they work great! they make the bed super solid and were painless to swap out. I like the metal wheels included because they have nice grip and are lighter than the stock plastic wheel. Only by a couple grams, but hey, every bit counts. Going to get more of these as we expand our Ender selection
