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

Works as advertised.

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.

I have these on all of my printers to give a stable height to my build plate. Steel springs, even the stiff ones lose strength over time. These silicone spacers maintain the height for a long time and reduce the need to fiddle with a printer. Time saved by not adjusting bed height is time spent printing parts. Very cheap peace of mind.

These have been great to really pull my printbed into tram/level.

This is an excellent idea. They work perfectly on my AnyCubic I3 Mega as well as my friends Ender 3 Pro. I’ve not had to re-level the bed once in the month since I installed these. Perfect solution.

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 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.

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.

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 had to buy spacers for them to work
