1piece High Temperature Sharp Hardened Tool Steel MK8 Nozzles 0.4mm for 1.75mm Makerbot, Creality CR-10 All Metal Hotend, Ender 3/ Ender3 pro, CraftBot, Prusa i3 3D Printer

I orderd .4 but what arrived was way smaller than that. Waste of money.

Quick delivery. Have to wait on a new hotend to try it out. Was getting horrible prints but I now do not think it’s the nozzle.

completely useless after 1.2kg of carbon fiber nylon, i tested brass for the hell of it and i was able to get 500g out of it, and e3d hardened nozzles got multiple kg of CF nylon through it.

All kinds of problems. Never had problems with any other nozzle. Decreased line width to 0.3mm, better, but still not there. I believe what should be a 0.4mm must be a 0.25mm. After hours of trying to get a good print, back it goes. Put back on my previous 0.4mm, and back to a perfect print.

Does what its supposed to do.

Worked as expected for wood and glow in the dark PLA. Seemed dimensionally accurate as far I can tell. As with other steel nozzles, you need to run it hotter.

Good nozzle. Prints as it should. No complaints

Easy installation

Works great. Wish I had tried 0.8 mm earlier. Such a time saver. Using it for carbon fiber infused. No clogging at all. Works great for all filaments though

Boy this puts down nice lines. Ive only printed PETG with this so far. My prints are smoother than they were with the stock Ender 3 nozzle.
