15PCS 3D Printer Nozzle Kit for Elegoo Neptune 4 Plus/Max - Brass, Copper Plated & Hardened Steel Nozzles (0.2/0.4/0.6/0.8/1.0mm) - Perfect for High Precision Printing, DIY Projects & Rapid Prototyping

This is an excellent assortment of nozzles for expanding your knowledge about 3D printing, and the value is fantastic. I've used my Neptune 4 Pro with 0.4mm, 0.6mm, and 0.8mm in brass, stainless steel, and hardened steel, but not every size in all materials. With this set, I'll be able to do that and more.What makes this great to me is that you get all 5 sizes in all 3 materials, which I've been unable to buy before now, even on other large, online markets. In my searching, the real outliers are the 0.2 and 1.0 nozzles because they are harder to use and very case-specific.If you've got a Neptune 4, grab this pack.
