8 Pieces 3D Printer Heatbed Parts Silicone Leveling Solid Bed Mount 3D Printer Heatbed Part Stable Hotbed Heat-Resistant Buffer Compatible with CR-10 Ender 3 Bottom Connect (Black,0.63 Inch, 0.7 Inch)

Yea these are what your looking, if you need one smaller, slice a bit off.

These solid bed mounts are not solid. Kinda squishy in my opinion. I was looking for something more solid.

Very inaccurate sizing, as each spacer has its own height. Measured each with my caliper and none were equal height. Luckily most print beds have adjustment screws to compensate for this poorly made product.

Simple and effective! I rarely have to make bed adjustments. I mean very rarely. And I will change out filaments frequently, without having to worry about adjusting my nozzle height.

Theyre silicone spacers for your bed. They work but you ideally want ABL or manual mesh leveling enabled because these dont squish as much as springs which makes manually tramming the bed nearly impossible. I like these over metal ones as these do have some give should your nozzle ever collide into your bed, which will prevent your bed from breaking.

if you are having bed leveling issues this will help a great deal I have them on my ender 3 and ender 3 v2 and a ender 5 plus the ender 3s i did have to adjust my end stops but that was no problem.

My bed stays level much longer after installing these.

If you add a bed leveling probe these are fine. Without a probe you need to be able to move the bed around and these do not allow for much movement. Compared to the original springs, and replacement springs too, these are MUCH stiffer. They do not all or much adjustment.

They do work but I ended up going back to the stock orange springs, these are really finicky to fine tune

after a careful set up and bed level I have not had to touch it for the last 50 prints.
