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 had to buy spacers for them to work

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.

Works like a charm, and I love it

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.

Works great on s1

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.

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!

Switched to these spacers and wont go back to springs. Way more reliable and hold level waaaaay better

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

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.
