3D printer owners, especially of Creality machines like the Ender 3, Ender 3 Pro/V2/Max, Ender 5 series, and CR-10 models!

This official upgrade kit tackles two common pain points: bed leveling and nozzle wear.

First, it includes sturdy red aluminum hand-twist nuts to replace the stock nuts on your bed leveling screws.

These are way easier to grip and adjust by hand than the small, often hard-to-turn original nuts.

Second, it comes with a set of stronger 20mm die springs.

These yellow springs are stiffer than the weak stock ones, which means your bed is less likely to go out of level from vibrations—you'll be re-leveling less often.

The kit also throws in some spare 0.4mm brass nozzles, which is always handy because nozzles wear out or get clogged.

Installing these is a simple upgrade: just remove the old nuts and springs from the four bed screws and put the new ones on.

It's one of the cheapest and most effective quality-of-life mods you can do to make 3D printing less frustrating.

If you're tired of constantly fiddling with bed leveling, this little kit is a total game-changer.
