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.

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

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.

The knobs are pretty big and easy to adjust. There is no market for direction but by now, you should probably already have this all figured out. The anodizing is a nice bright red and not dull like a lot of the cheap parts. The rest of the parts in this kit are also quality. I’m using the springs rather than The spacers o this printer because I don’t have auto leveling but they seem good too so I’d used them when I upgrade.

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!

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 recently picked up a used (Amazon Return) Ender-3 and have been upgrading it. The stock bed springs leave something to be desired. The spring rate is very low and I noticed the bed had a lot of wobble and movement while printing. This kit comes with stronger springs and silicone mounts. I decided to try the more solid silicone mounts first, and they work great. I have not tried the springs from this kit as the silicone mounts worked so well, but I do have concerns with my particular printer. When levelling my bed I noticed that it sits very low to the mounting plate, which means that the springs would be compressed a lot. Looking at the springs, its possible they would not work on my unit. Its possible the coils would bind before I could get the bed leveled. The metal bed leveling knobs included in this kit are a nice upgrade. The stock ones were hard to turn because they were so small that the bed got in the way. That being said, these knobs could also be 10-15% larger. The back knobs are still very hard to get at. They also do not have the labeling on them to tell you which way to turn them to raise/lower the bed. Once you realize the screw is upside-down, so lefty-losey (Raise Bed) righty-tighty (Lower Bed), it is easy to remember but would still be nice to have the labelling. The hotend that is on my printer is not the stock one. The person that owned it before me upgraded it. This means the included nozzles are not the same type as my printer uses. However, they will work in my Anycubic Mega X. They are going in its extra nozzles bin. For the price, this is a pretty good kit. A stock Ender can use all the parts and the choice between the spring mounted or silicone mounted bed is nice.

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 highly recommend these upgrades. The silicone spacers are a must if you have ABL. If not then use the heavy springs! Best upgrade kit for any printer!

This is a very nice upgrade kit for your printer. The red anodized aluminum leveling nuts are very easy to operate and definitely better than the plastic ones which probably come with your printer. They are not crusty in the threads so the screw on easily. As they say the springs are a bit larger than those which come with Ender series printers, so you will have to address that. The silicone bed spacers to used as replacements for your springs are fairly dense but have enough spring to them to be good at shock absorbing and absorbing some pressure. The nozzles all look to be fairly well made, although it looks like some may not be cut of level on the extrusion end. My eyes arent so good and I dont have any magnification to inspect them closer. So they are the only potentially disappointing aspect of the kit.
