8 Pieces 3D Printer Heat Bed Leveling Parts, Silicone Solid Column, OD 0.63 Inch ID 0.16 Inch Stable Hot Bed Tool Heat-Resistant Buffer Compatible with CR-10 Ender 3 Bottom Connect, Black

I have these and others like it on all 5 of my printers, some of which have auto leveling on them. I still have to level all of my printers that dont have auto each and every time before I print. Either I am doing stuff wrong or the hype isnt what its cracked up to be. They do though help mitigate the ringing in prints so theres that. For the price they arent too bad.

For an ender 3 bed there should be one that is a little bit shorter so that it fits well under the heated bed cable brace, well in this kit there is not a shorter one it is 8 or the same size. You can still make it work by tightening down the one with the brace alot but i would reccomend just finding some that are the right size. Please dont waste your money like i did.

they are all the same size so you have to cut one to fit in the cable corner of your printer bed.

I have replaced the springs on all of my 3d printers with these and would never go back to springs. These are so much better. I highly recommend them.

Works as advertised.

I think these are a major upgrade from the springs. More even leveling it seems

Do not hesitate to upgrade your bed. The stock springs are garbage. These worked for me. I first got them as rich by as they’d go. Raised the z axis and leveled from there. Prints have come out much smoother and haven’t releveled the bed in a week.

These are really made for a beveled screw as they are cut for them so there is a cup of you dont have them and my CRX pro didnt come with them so its not 100% match and made adjustments with autolevel and didnt see much of a difference that manual as I still have to adjust the Z offset -+ 1-.50

There are so many types of springs and I feel like Im always releveling my bed but with silicone spacers after I set it Im good for weeks at a time.

I replaced the standard bed springs on my CR-10 mini with these 6 months ago and dont need to check the level as often as I used to. I did need to add a couple of washers on top and bottom as shims to tighten up the columns so they are more responsive to adjustments. It was a little loose with just the columns.
