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

These were exactly as advertised. You get 8 of them, all 18mm tall. You need four of this size for an Ender 5 Plus. Time will tell, of course, but the initial impression is of good quality at a good price.

Bought these for even leveling and a stable bed adjustment. They do what theyre supposed to while having a little cushion and a little rigidity at the same time. They fit my Ender 3 S1 just fine.

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

I don’t know why there is a difference between the orange and black spacers, but the orange are better and often cheaper than the black version.

Switched to these spacers and wont go back to springs. Way more reliable and hold level waaaaay better

Ive only had them on for a few days, but so far they are holding up well. I prefer this greatly to the solid plastic standoffs that come with the Kobra Go. They hold solid while allowing for more adjustability to aid the ABL and have given me great prints so far.

First of all, They do not look like the picture. No core and over all a bit cheap looking. All are the same size, I had to cut one to fit in the back where the heating wire for the bed are. I will keep them and see what happens.

I love these silicone columns. They are great spring replacements. These plus a dab of thread lock on the bed bolts and I havent needed to relevel my bed in over 8 months. Measured at the bolt locations with a probe, the bed is just a level today as it was when I installed these.

Ive used simulare ones, But these were described as having solid core that appealed to me. But when they arrived they had no solid core. Appeared to expand and shrink frequently based on not being able to get consistant results. As soon as I got my bed level and ran another test to verify last test my bed was off level. Unable to get consistant result even without adjustment from one test to the next back to back. At first I thought something was wront with my ABL sensor so I replaced with old simular ones I was using from another manafacture and I was back to getting consistant results. Luckily these werent expensive but not worth the money.

Works as advertised.
