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 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.

The metal leveling nuts are much more durable than the stock plastic ones and they hold their level much better. The springs are also much stronger than the stock ones and they help to keep the bed level even when you are printing large objects. The nozzles seem to be good quality and I have not seen a decline in quality of my prints. The silicone leveling column mounts are also a great addition and they make it much easier to level the bed. Overall, I am very happy with this product and I would definitely recommend it to anyone who is looking to upgrade their Ender 3 Pro.

I’ve got 5 printers and have ordered kits like this for at least 3 now. The spacers are so nice. Worth every penny

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.

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

Decent upgrade.

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.

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 picked up an older ender 3 from a friend and Ive been upgrading it to get it printing better. This kit comes with some of the best updates you can do for the printer. 1. The yellow springs - The original ender came with really weak springs which causes the bed to move some which is not good for 3d printing. Around the time the ender 3 max came out Creality moved to using these really stiff yellow springs for the bed. I have compared the springs included in this kit to my ender 3 max springs and they are identical with the same strength. The springs are good 2. The bed spacers - If you opt for the auto levelling kit then instead of springs you switch to using these bed spacers. You want the machine doing the levelling not you. These spacers are sturdy and look exactly like the creality kit. 3. Levelling wheels - Ok, this one is more cosmetic as the plastic wheels are fine but I do really like them. They are machined well and that anodization is perfect. 4. Spare nozzles - These nozzles should last a long time. Look like your typical brass nozzle. This is a nice kit for the price.

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