ENOMAKER Upgrade PTFE Coated Nozzle 0.4mm MK8 Non Stick Anti Stringing Extruder Tips for Creality Ender 3 Pro V2 CR-10/S4/S5 3D Printer Accessories（Pack of 6）

Works great

The non stick coating started to chip off when tightening into the extruder. Then got worse from there. I won't be buying any more.

So i bought these when it had 0 reviews but i bought a bunch of nozzles to try, and out of all the ones i bought these fixed my issue with stringing, i was worried they would be bad, but my goodness they are awesome, i have an SV06 which is bad with stringing and since switching to these nozzles, i havent seen a single string i spent days messing with settings trying to figure out why i was stringing, i switched nozzles 5 plus times, but these just work, and work well, will for sure buy another pack to have on hand

Got these due to stringing with petg causing buildup on the nozzle and failed prints.This won't stop all of it, and you do need your slicer settings configured properly and your z offset set correctly. Once all of that is done though, if you do have any remaining fine strings they won't build up nearly as much on the nozzle.Now if it's really bad you can still get build up on the heat sock but that's much easier to grab off with tweezers mid print.Do not use metal tools on the nozzle when hot they will scratch!

I used one of these nozzles to print something with soft PETG filament and it is now destroyed. I don't know how contact with PETG made the coating come off the brass but it's gone. There's a small patch here and there.
