300mm Z-Axis Lead Screw For 3D Printers – 8mm Diameter, CNC.BZ – RepRap, Creality, Prusa Compatible

Need a replacement Z-axis lead screw for your 3D printer?

This one’s 300mm long, 8mm in diameter—pretty standard for a bunch of DIY and prosumer machines.

It’s brand new, still sealed in the original packaging.

Brand is CNC.BZ, and they didn’t assign an MPN or UPC to this one, so if your system needs those, just know it’s blank.

But the part itself is solid.

Great for upgrading, replacing a bent screw, or even building a printer from scratch.

Simple, no-fuss component that gets the job done.

Threads are clean, and the length gives you decent Z height for most setups.
