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 work very well and were an easy swap - not sure how they want me to judge print quality based on these parts - but i do have really good quality and it works well.

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.

Decent upgrade.

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!

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.

Having several printers and are like all the same can be quite boring in a way. Upgrading is also a learning experience and funner too. Giving the printer a touch of class being aluminum adjusters that are red instead of black plastic ones makes it look different and sets it aside from others. I do like the idea of rhe blocks for the build plate instead of the springs. I have the option to use the heavier type springs if wanted but first time for the blocks. Ive seen where the blacks are also aluminum then makes it non adjustable for little movements but with the rubber there still can be slight adjustments that can be done. Have not needed to change the nozzle for the hotend but now I got 4 that can be replaced with when needed. I like this kit and the cost is really reasonable so when ready to upgrade another printer it wont be an arm and leg for the cost. Material looks and feels great and quality is expected to last for a long time. Hope you will give this a try too and Good Luck. Have fun upgrading.

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.

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 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.
