Official Creality Metal Leveling Nuts with 20mm Die Springs and 0.4mm Nozzles, Red Hand Twist Nuts Set for Ender 3/3 Pro/3 V2/3 Max, Ender 5/5 Plus/ 5 Pro, CR 10 Series 3D Printer Bed

These are a must have for your printer much stronger and look good

Stiffer springs and aluminum wheels, are a nice upgrade, letting you level the bed less often. Extra nozzles are always welcome as it is often more work to unclog a nozzle than to just replace it. Buy it for the springs and wheels, stay for the nozzle replacements.

These are beautifully made and they work really well. Word of caution though, especially if you have the ender 3 Pro and a glass bed. After installing these you WILL need to adjust your Z axis because these springs are a longer than the stock springs so you will not be able to "home" without smashing your nozzle into the bed. I'm new to 3D printing and that's what happened to me. My bad but hey, you live and you learn. But yeah get these they're good.

This will fix issues with Bed Leveling adjustments that occur regularly with you're Comgrow Ender 3, 3Pro and 3v2. I couldn't get any response from what is supposed to be Comgrow's Customer service and realized that was a dead end... NO Support. So gave this a Try and it fixed the Issues.

These springs are stiff and keep your bed from off-leveling over time. The red dials are anodized and have a nice premium scarlet finish to them.

Great kit came with bed knobs and nozzles had to but after getting cheaper knobs that didnt have a high enough center.

The springs and adjustment wheels are great, no issues. My complaint is with the nozzles. Either I got a return where someone switched them out, or they’re not actually 0.4mm… Been fighting issue after issue, swapped nozzles like 4 times, finally decided to compare the nozzles I was using (the ones that came in this kit) to my other set, and sure enough they are NOTICEABLY bigger. Should’ve been the first thing I checked, but live and learn.

I level my bed and don’t really have to do anything again

Si tienen una Ender3 V2 con sticker magnético y cama magnetica, los resortes no les van a funcionar ya que quedan al tener más material no permiten nivelar la cama, ya no baja más.

Les ressorts sont trop raides et trop longs, il faut enlever (couper) 2 spires pour que cela fonctionne bien .Après c'est le top.
