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

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.

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!!

I love these because I spend way less time tramming my bed. Once Ive gotten the bed level it stays that way for many many prints.

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

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.

I had to buy spacers for them to work

Works as advertised.

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.

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
