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

Works well

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.

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.

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

About 5mm too long even when springs are fully compressed, hopefully the printer wasnt damaged when it auto homed...

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.

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.

I bought a used printer and the leveling springs were shot, I put these on and leveled my bed perfectly the first time.

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

The included bed leveling springs are too long so I wasnt able to use those without any modifications
