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 had to buy spacers for them to work

These are probably the best upgrade that Ive done to my ender 3

compared to the springs I was using, I had to add spacers or reset my z axis sensors zero location. I added a couple washers to get a little crush on the spacers rather than totally reset my zero height

Works great on s1

I bought these for my Dreamer and they fit perfectly. Really had to tighten them to be able to level the bed, which is what I was looking for. I was having leveling issues on every print and noticed the spring were very weak, so I went this route. I also noticed some nuts coming loose, so I tighten them as well and used thread locker. No problem with my first print, and the bed is solid and the adjustment knobs are tight, so they won’t back out, causing the leveling issues I had. Now to see how they hold up in the next couple of months.

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.

Fit perfectly on my creativity ended-6 cycle core

The OEM springs are OK. The upgrade springs are probably better, but I am absolutely loving these! I got my bed set, and haven’t had to make an adjustment in a month! Heat doesn’t affect them, and neither should constant compression. These are great!!

no photo sorry! but these are nice! i got them becuase i was rebuilding an older printer and figured for the price ill check em out. I am pleasantly suprised at the tenacity of these so far, i can recommend 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.
