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

Good price on excellent quality product

This will fix issues with Bed Leveling adjustments that occur regularly with youre Comgrow Ender 3, 3Pro and 3v2. I couldnt get any response from what is supposed to be Comgrows 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.

These are sold as an upgrade. Stock is as good or better. Waste of time and money

Great upgrade for ender 3. It would be awesome if they added a 5th yellow spring for the extruder replacement. Good spares to have on hand for sure.

Love these knobs and springs. I do not have to level my bed as often!

The springs are nice and stiff and the nobs are a great color and sleek. Easy the level a bed with this combo

Springs are a lot better over stock V2 springs and the handles are a lot easier to handle over stock. Great small, cheap upgrade.

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. Im new to 3D printing and thats what happened to me. My bad but hey, you live and you learn. But yeah get these theyre good.
