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

My first go around of ordering this item came with disappointment as I received an empty parcel. I just received the replacement today and Creality threw in some .4 nozzles for the trouble. Think Im going to stick with printing with Creality. <3

Easy to install, great upgrade for my Enders 3 Pro.

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.

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

Perfect fit. Very necessary upgrades.

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

Worked perfectly first time. Has been in use now for 3 months with no problems. Would buy again.

I wasnt sure these springs would make much of a difference on my old ender 3 but I am happily mistaken to see that I was wrong. The print quality has really improved and I dont have to level my bed after every print which increases my productivity.

They are nice and stiff, but are too large to fit the ender 3 print bed. I had to crank them down all the way to fit under the extruder nozzle at home position. They were fully compressed and still didnt fit the bed under extruder.

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.
