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)

Love these wheels versus the plastic ones that come on my Ender 3. I do love that the silicon spacers are two different sizes to overcome the bed heater holder/protector. Look great and work great.

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.

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!!

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

The Bigger wheels are much needed. Springs are definitely an upgrade if you are looking at a middle between stock springs and silicon spacers.

I ordered this accessory kit to test the silicone leveling spacers and they work great on my Ender3 V2 Neo. The bed is really rigid now. These spacers will work on almost any Creality Ender 3 printer except for the Ender 3 S1. The S1 requires the spacers to be the same size due to a different design for the bed strain relief. Three of the spacers measure 18mm and one is 16mm. The aluminum bed adjusters look awesome and add a nice custom touch to the printer. The nozzles are the standard .4 brass and work like stock ones. Great kit.

Used the rubber stands instead of the springs because i was tired of constantly having to adjust the springs which would always lose tension or have to be adjusted. The bundle itself is more then worth the price, including extra nozzles, springs, upgraded knobs and the rubber stands!

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

Using on an Ender 3 Neo. Swapped out the old plastic bed adjustment knobs for these aluminum ones. Silicone spacers hold the bed level longer than springs in my experience. Good value for the price!

This is a must-have upgrade set. The springs are keeping my bed consistently leveled, and I had no idea how much easier it would be to level the bed with these oversized wheels. Big improvement.
