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 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.

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.

I have an Ender3 S1 I would have to level my plate after every print. Since replacing the springs that came on my machine with these I haven’t had to level and I have printed 15-20 times since installing! So happy!!

Works great on s1

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.

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.

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.

Tired of having to fiddle with your bed adjustment each and every print? Install these babys and the screws stay tight and minimize the amount of adjustment you have to do each print! Well worth them money!! I added a small stainless washed above and below the piece to even out the squish - Used on a tronxy xy-2 pro and a voxlab Aquilla

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.
