32PCS Mk8 Nozzles 3D Printer Extruder Nozzles Hardened Steel, Stainless Steel, Brass High Temperature Pointed Wear Resistant Nozzle 0.4mm,Compatible with CR-10, Ender 3/ V2 Ender3 pro,Prusa i3

This is a handy mix of nozzles in the most common sizes. The hardend steel is particularly useful for slightly abrasive filaments. It would be nice if the pack had 0.6 and 0.8 in the hardend as well, but for most people this set has all you need.

yea, seems OK. no complaints

This was supposed to have 50 pieces .4 nozzles but it only had 24 .4 and 2 each .2, .6 and .8. Not a huge deal for myself as this is probably a lifetime supply but if you actually need a lot of nozzles you might want to shop elsewhere.

These do the job well on my 3D printer. They all appear to be good quality. Ive used several of the sizes and styles with no clogs yet.

I tested the hardness of the steel nozzles using a indentron hardness tester. The actual values were half of the advertised value for HRC. Do not use if you actually need a hardened nozzle. Values of HRC were between 24.9 - 27.7

The nozzles seem to be as advertised. The steel ones stick hard to a magnet, so theyre the real deal. The stainless dont stick at all, but that doesnt really mean anything. The one truly phony thing is the needles. They are all the same size and they measure exactly 0.34mm-they are neither 0.4 nor 0.5 as advertised. I have purchased other needles for sizing, and they are that same 0.34mm size, so all I can say is that each nozzle here allowed the needle to drop through easily, so none of them are undersized. A good set that covers many filament scenarios. As advertised except for the needle nonsense.

These do the job well on my 3D printer. I have used the 0.2mm, 0.4mm, and 0.6mm nozzles successfully. They all appear to be good quality. Having a nice selection of nozzles on hand for different printing tasks as well as emergency replacement is essential, and these do the job nicely.

Ever since I got these I thought something had gone wrong with my printer. No amount of adjustments would help. Regardless of whether the steel or the brass, the prints would always come out awful. I started noticing that when I did get good prints, it was from old nozzles I had. Finally I started testing these nozzles with the same configuration against others I had of the same size (the only difference was making sure the bed was leveled each time.) Without exception I had great prints with other nozzles and awful with these.

I can’t speak on the over all quality because I am on my first one with only around 6 hours print time. But for inexpensive nozzles they appear to be quality.

Havent used the steel nozzles, but the brass is working awesome! I test each new nozzle by pushing a cleaning rod through it so it was nice these came with them. Installed easily enough using the enclosed wrench and went right at an 18 hour print. Im impressed. Money (and not a lot of it) well spent.
