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

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 had to buy spacers for them to work

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

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.

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

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.

Works like a charm, and I love it

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.

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.

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.
