FYSETC 3D Printer Ender 3 S1 Pro Ender 5 Plus Heat Bed Leveling Part Silicone Solid Mounts Column OD 0.63in ID 0.16in Stable Hot Bed Tool Heat-Resistant for Ender 5/ Pro A8 Wan hao D9 Meg- Pack of 4

These took just a few minutes to install. After tightening them all to feel about the same tension, the bed was nearly perfect before even making any adjustments. Ran the auto level routine and made very minor adjustments. Feels much less prone to unwanted movement compared to the factory springs.

Works great. Tightened bed down each bed wheel approx. an equal number of turns on all sides until I could feel that the spacers were forced up against it, then went through my normal leveling procedure of the four corners and Z offset. They're working great nearly 2000 print hours later.All four of these are the same size, just a disclaimer for you guys out there that need three of one size and one of another. If you have the S1 or S1 Pro this will be the set you want to use.

They are a bit small, but otherwise nice and sturdy and are great upgrade from the Stock Springs!

Replaced the stock Ender 3 S1 bed springs with these mounts several months ago and am happy with how well it maintains bed height. Previously, while using the springs, I'd need to do major adjustments at least once a month - but with the silicon mounts, I have not had to do any major adjustments - only minor ones due to filament type changes.I would say that best results is when the mounts are under a bit of tension which would require lowering z-offset a bit more than usual.

I read all the glowing reviews about these and figured they were a worthy upgrade. Pros: they are silicone and have a bigger area of contact with the bed.Cons: not the easiest parts to install and to complete installation cleanly you need to print out out a couple wire management parts. Not terribly difficult but not a just plug and play thing. Biggest issue is I noticed the silicone swells and then shrinks and I felt like the bed would get warped. I have no evidence of this but just basic physics of the rigidity of the silicone and the size of the spacers gave me this concern. I went back to stronger upgraded springs and am much happier.

I've been struggling with keeping my bed level for months prior to purchasing these silicone mounts. No matter how much time I would spend leveling my bed prior to printing, the weight of the finished print would compress the springs and ruin the level. Since installing these silicone mounts, I only have to adjust my bed every few weeks. Most of the level work is now taken care of by my auto bed leveling (I'm using BLTouch).Warning! Your bed will no longer be "compressible". If you set your bed level incorrectly, your printer head may crash into your plate and cause a lot of damage. With the springs, you have a small safety net because they could compress if your printer head moved into your build plate. This will not be the case with these silicone mounts. Make sure you very carefully level your bed initially and carefully calibrate your Z axis prior to printing.

Replaced the factory springs on my Ender 5 Plus and these are night and day for leveling, highly recommended will save you hours leveling!

Converted the bed leveling on my QiDi Tech X-Plus using these and they fit perfectly. These are a recommend for anyone planning on doing the same.
