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)

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.

They work pretty good. I find them to be a bit stiffer than the springs.

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.

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

I havent leveled my bed nearly as much as before, and Ive used 3 different kinds of springs trying to get a more sturdy print bed. I HIGHLY recommend this product. And getting 2 sets is amazing, especially since I have 2 identical Ender 3 printers.

These are a great replacement for the sprimgs provided by the factory. The bed no longer needs to be elveled after every print.

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.

im getting more reliable mesh in kipper

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

Stay in place without having to readjust bed leveling here and there every so often. Works so far without issues. One of those cheap upgrade with big returns. I put it on my ender 3 v2. With no issues.
