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 put these on my Voxelab Aquila X2, and found it to be a very big upgrade over the original springs!

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.

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.

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

Works as advertised.

It seems to do what it is suppose to do

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 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.

I have replaced the springs on all of my 3d printers with these and would never go back to springs. These are so much better. I highly recommend them.

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
