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

The OEM springs are OK. The upgrade springs are probably better, but I am absolutely loving these! I got my bed set, and haven’t had to make an adjustment in a month! Heat doesn’t affect them, and neither should constant compression. These are great!!

I think these are a major upgrade from the springs. More even leveling it seems

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.

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

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

Please do not get me wrong as it is I am one of the strongest proponents of Silicone Bed Mounts I really am. Here is my argument FOR Silicone Bed Mounts: The reason that Silicone is FAR and I mean FAR superior as a bed mount compared to Metallic based springs is due to a simple argument called stored energy. Metallic based springs have significantly more stored energy when in their compressed state compared to that of silicone based mounts (when compared in a similar shape for both the metallic springs and the silicone based bed mounts ie both are cylindrical and go around the bed screws <<<<----- this is what I am comparing as to keep apples to apples as much as possible). If lets say you had a gun of sorts like a sling shot but could mount the metallic and or silicone based bed springs/mounts. I guarantee whenever you instantly release the metallic based springs from their compressed / energized state that would fly significantly further than that of the silicone based bed mount. Simple argument right? Its really that simple. So now lets think about Metallic based springs that are compressed under your bed/print surface. Any sort of movement, especially the faster you print, only assists the springs in their efforts to go back into their uncompressed unenergized state and thus makes your bed become unlevel significantly faster than that of its silicone counterpart that performs the same function. Every single time you lift a print off of the bed surface whether it be through a lot of effort or not much effort at all, regardless of the amount of effort it took to get that print off that little bit of wiggling only angered the metallic spring in such a way that it made your bed unlevel. Those metallic based springs when in their compressed state are trying to move in any sort of direction (literally) possible in order to return to their uncompressed state. Imagine when you pinch a spring in between your thumb and fingers. Remember how that spring will try to wiggle in any sort of direction possible in order to become uncompressed again? That is the beauty of springs when in a very constrained environment and yes the bed screw does place the metallic spring in a somewhat limited yet constrained environment though regardless it is still trying every possible which a way to become uncompressed again. SO yeah that is the beauty of metallic springs but it is a curse for the leveling of your bed. Ive heard some argue oh well you need to tighten the springs all the way down til they cant compress no more then loosen three turns or something of that nature. Rubbish I tell you!!!! Absolute rubbish. Yeah that might be the best way to make metallic based springs work well but that is simply NOT needed at all with silicone based bed mounts. Ok I think Ive beat the horse dead so if I have not convinced you at this point that silicone bed mounts are the ideal material/solution for a more consistently level bed then I dont know how much more I could say to convince you otherwise cause you are clueless and maybe 3D Printing isnt for you!!!!!!!! LOLS Now about this particular Solid Column Silicone Bed Mounts. There was not any sort of Solid Column in my order of Silicone Bed Mounts. I even cut 4 of them open to have a look inside to if there was in fact a solid column of which I found none. This is disappointing cause the only thing I could see as better than silicone is silicone with a solid column embedded inside as to aid the silicone in maintaining an even more level bed over a longer period of time than they would normally. WHich by the way is a much more considerable length of level/tram time than compared to that of its Metallic based bed spring/mounts. Ok that is all Ive got I just wished that I would have got the silicone mounts that actually had a solid column other than that for 7.59 USD getting a total of 8 silicone bed mounts is a really good deal IMHO and isnt too too disappointing if you dont get the solid column in your order. BUT if you already have silicone bed mounts like myself and are looking for an even longer length of time on your bed being level like the solid column inside silicone can offer then Id order a different brand cause this particular order I got was disappointing to say the least!!!!!!!!!!!

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

Works like a charm, and I love it

Works great on s1

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.
