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)

Have a caliper on hand if you intend to use these. Was struggling to get my bed level and finally decided to measure them. The others were within .06 of each other but one was not. The one measuring 17.66 was supposed to be part of the set of 6 larger ones but due to apparent lack of QC it was noticeably different from the other 5.

Used these to replace the stock hard spacers on the Creality CR-6 SE and CR-6 Max. Allowed for fine adjustment of the heated bed to get it leveled. Their larger diameter made them easy to install as they stayed in place while trying to align the heated bed to the carriage.

I hardly have to relevel the bed now. Set it and forget it.

DO NOT BUY THESE! I bought them thinking they would make for a more solid mounting solution. Unfortunately, these silicone spacers deform when under continuous pressure. After each print, my bed would be entirely unlevel. These made it so that I had to re-level after each and every print. These are absolutely awful.

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.

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

I bought heavy duty springs, printed many spring caps. These are awesome. Lightly tightened them, used Octoprints bed visualizer and started tightening as needed. The bed is level and has stayed level. Im glad I tried these.

I got these because even with the yellow bed springs, I was having to adjust the level after removing parts from the heat bed. After using these rubber mounts and tightening them down with a little bit of crush the bed seems much more firm and I get less rocking during the print and havent had to touch the level in several prints. This seems to be an improvement over both stock and the yelllow spring upgrade. Worth the money.

No combo worked with my ender 3 pro... just opted for the heavier duty springs... not worth returning.

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.
