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

I’ve expanded my horizons trying out all of the different sizes nozzles- some prints that don’t require a lot of detail are printing in half the time now feom usi mg the larger nozzles. Awesome!

A++++

Cheap and clogs. Getting refund

No matter what 3d printer you have, you will eventually need to replace the extruders as they wear or you encounter an issue. This kit provides a decent variety of steel and brass replacements in several sizes, so that you can adjust your extruder to both the type of filament and size of filament desired...some filaments are more abrasive than others and sometimes a wider filament does a better job depending on what you are printing. The extruders are reasonable well finished, and the interiors (where it matters) were smooth on the kit I received. The threads were clean and swapping out the extruders did not come with the feeling of imminent cross threading, which would have required replacing the heads.

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.

Prints really stringy with these nozzles, switched back to original prusa and stringing went away

Exactly what I needed.

This was a really nice kit of assorted nozzles. I thought it was an assortment of brass and steel but it was various sizes as well which allowed me to discover a whole new world of printing. I love a .6 nozzle and would have never have intentionally tried/ordered a .6 nozzle. Not sure what other products this seller has to offer but I am very satisfied with this purchase. Happy Printing.

This is a great buy for any 3D printer owner. At this price, replacing the nozzles is a sensible alternative to the challenge of cleaning them. (But - obviously - you can still hold onto your old nozzles and do a big bulk cleaning to run them through the use-cycle again... Still - these are great.)

Nozzles are showerer than expected for a Prusa MK2.5s and Prusa Mini. This means you will hit the heatblock without an gap which will cause you to have a filament leak. You will need to adjust your heatbreak down to close the gap but you may not be able to. These are usable but it would be better to get nozzles that are the right length.
