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

Worked fine at first...I printed with pla with carbon fiber but when I switched filaments to regular pla had nothing but issues with clogging. I tried various clearing methods to clean out the nozzle but still clogs.

the top of the threads is a mating surface with the heatbreak and on my nozzle there was a casting error where it was not sharp and flat like in the pictures. It caused a leaking nozzle and forced me to lap smooth this surface by hand and thats not very good bc i dont have a good holding jig to keep it perpendicular. Well try it tonight to see if this helped, but so far im hoping that im only one of a handful that experienced this.

Great nozzle, well made. If you need tougher than this, get ruby nozzles. For everything else, this is all you need. Dimensions, threads, and interior polish are spot on and the aperture is centered with good wall thickness. Angle is appropriate for non-planar FFF.

Good quality nozzle. Direct replacement for our CTC Bizer (Makerbot Replicator clone) printers. I havent tested with an abrasive filament yet, but the nozzle seems great!

I believe the price I paid was fair, but according to the picture in the description of the item, it was stored in a plastic container. When I received my item it was in a small plastic bag which was put into a very big bag mailed to me.

The nozzle is too short. It sits too deep into the nozzle assembly, and you cant get the wrench on it to tighten down.

The threads are WAY too short to work for a Prusa i3 MK3s. The heater block will have to thread in so far that your carriage WILL melt.

I am not an expert, but I bought this for printing wood PLA and it just does that.

No cons to speak of. Print are fantastic using this nozzle. Great for CF filament.

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