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

Easy installation

I received a nozzle with 3 dots on it like the listing says for the .4mm. However the nozzle is far smaller than even my .2mm nozzles. I didnt notice and ended up having to spend a long time unclogging my machine. Im going to shop on ebay for now on for nozzles since this isnt the first time I received the wrong size.

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.

Lasted for 8 prints ...... dumb for the price super disappointed for the price brass lasted longer

Good tip. No issues happy with it

Nozzle was not .4mm like advertised, closer to .2mm. Save your time and buy a MicroSwiss or something else reputable

Not actually 0.4mm it’s slightly smaller, and clogs constantly.

I bought the 0.25mm nozzle and really like the detail it produces at 0.1mm layer height. It does take forever to print with those settings. Also remember to raise the temp by 5-10C as it is a steel nozzle. Thermal conductivity is less than brass. No issues so far. Used on both PLA and PETG. No abrasives yet, but I will be trying it with glow-in-the-dark very soon.

So far Ive printed a 2KG of Carbon Fiber PLA and 1KG of Wood PLA with no wear to the nozzle, its impressed me so much I returned and bought 6 more nozzles to keep around and hand out to other friends.

Treading all wrong destroyed heating block. Only wish I could rate it lower
