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 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!

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!!

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

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!

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.

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.

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.

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!

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.
