3D Printer Die Spring 8mm OD 20mm Long Light Load Compression Mould Die Spring, 12 Pack Yellow Heated Bed Springs for Creality Ender 3s Bed

I used these with an Ender 3 V3 SE. While that printer doesn't have knobs to adjust screws, it'll work with them just fine (you just have to use a screwdriver on the screwed under the build sheet) instead.They did great. My bed is now super level. It's a cheap and easy upgrade for printers that use plastic spacers instead of springs.

These should be a standard upgrade for everyone. I put them on all my printers.

I upgraded my my Creality 3 Pro with them. They are not easy to install because of the printer not the springs. They work very well though.

Just your basic springs. Each spring came painted a slightly different shade so I doubt they're what you'd call a precision matched set - but if you're using them to preload a 3D printer bed you don't care. They're fine - get them. You don't need those dumb aluminum tension wheels but seven bucks is always handy.

I added these to my Ender 3 while I was putting it together. Much stiffer springs!

Definitely an improvement over the stock springs on a 3v2. Not sure if there is any actual print quality improvement, but it does seem to hold its location better, and it just overall feels more substantial, which is nice

More rigid than the original Ender 3 springs - requiring fewer re-calibrations than the stock machine for me.

These springs, along with a feeler gauge, will completely fix your bed leveling issues. No need for automatic bed leveling kits! Just remember to remove the build plate BEFORE removing the print from it! Also, do yourself a favor and install Jyers.
