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)

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.

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.

I was having trouble with one of my original plastic adjusters just not staying set. This kit has solved that problem. I love the metal leveling nuts they hold much better.

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) First impressions: Nice upgrade set of leveling nuts and springs. All of the parts look well made. Installation/setup: Follow instructions to install and adjust. Final thoughts: I’m new to 3d printing and I have no idea if this helps or not. I have to assume it does, it seems to work well. The ones that came on my second hand Ender 3 pro were worn from use and I got these to replace them. ⭐️1 star - I dont recommend it at all, poor quality. ⭐️⭐️ 2 stars - I dont recommend it, it has multiple faults, or a very high price. ⭐️⭐️⭐️ 3 stars - Its passable, It has some faults but the quality is ok for what it is. ⭐️⭐️⭐️⭐️ 4 stars - Product quite acceptable, it does what it promises. ⭐️⭐️⭐️⭐️⭐️ 5 stars - Product that I totally recommend.

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.

Decent upgrade.

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.

Exactly what every Ender 3 needs out of the box.

The springs that came with my Ender 3 V2 Neo are more robust than these replacement springs. The silicon column mounts are not an improvement. I do like the large, aluminum nobs but they do not lock in place when adjusted. These move while the printer is working. It is clear that the bed leveling system on my printer can be improved but this is not the way.

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.
