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 just have to say, wow, what a noticeable difference getting rid of the springs on my ender! Comes with stiffer springs and silicone spring replacements. Easy to install and comparable in price to many other options.

Not sure why nozzles are included in this set, but hey, what a bonus! I always prefer the red aluminum leveling nuts over the black plastic versions. They wont improve print quality or have any significant impact on your prints but they look great. They are also easier to adjust. The tighter springs will help keep your bed level for longer periods and will make adjustments easier. This will have a positive impact on the quality of your prints because everyone knows the secret to a good print is a good first layer, and a level bed is necessary for a good first layer! The silicone mounts are meant to replace the springs when your printer has an auto leveler such as a BL/CR Touch or an EZ-ABL (or equivalent). You will install these, tram your bed and then let the auto leveler do its thing.

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.

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!!

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 installed the metal leveling knobs and springs on an Ender 3 Pro. I like that the original knobs had the up/down arrows on them, but its not hard to remember which way to turn them. The metal knobs are roughly the same size, but look and feel better. The threaded area of the metal knobs needs to be a little taller, as it is the knobs are very close to the carriage and sometimes rub it when youre adjusting the bed. Its not a big issue and you could add a washer to space it out a little more, but itd be nice if they added a little length there. I like swapping to the upgraded springs and have used these on any printer with the cheaper silver ones. With the upgraded ones I get more consistent bed leveling that seems to hold longer. Theyre a simple, cheap upgrade that improves print quality some and makes maintenance and tuning easier. I havent used the silicone spacers yet, but Im planning to use them on a CR-10 Mini that Im adding ABL to. My hope is that the silcone spacers will give more stability than the springs, but still allow for some manual adjustment, if needed. I think this is a good upgrade set and I like that you have options for the bed spring upgrade. Especially since you can use them to upgrade the springs on two machines, like Im planning to do. If they extended the threaded area of the knobs then it would be a 5 star set.

This is a good kit with the MK8 nozzles and silicone spacers that most bed slingers can benefit from. The red wheels are just a bonus and in my opinion dont improve anything but looks. But this kit is the same price as a pack of the silicone spacers I got a couple of years ago for my first printer so great value overall.

Works as expected, I just have some slight issues with one of my screws moving by itself but that is a known issue that I need to get some lock nuts to fix. Makes turning some of the bed leveling sides easier than before but at the same time one of the corners is a little harder to turn because of the limited area under the heater bed. Overall though these work as they should with no issues, all the issues I am having have to do with the machine itself rather than these not working properly.

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.

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
