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

This was an easy install and an upgrade for my voxelab aquila. I had no issues and easy to level and balancing the heat plate when printing projects. It is definitely a great investment for the price. It also came with an extra set! 10/10 in my book!

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 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.

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

Fit perfectly on my creativity ended-6 cycle core

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

Works as advertised.

I have been using this for a few months now on an old Monoprice IIIP and have only leveled the bed once since installation. Get you some and quit with having to check you bed level every print.

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.
