WINSINN Stainless Steel MK8 Nozzle 0.4mm Works with Creality Ender 3 5 CR10 CR-10 CR10 Anet A8 for 3D Printer Hotend Extruder (Pack of 24Pcs)

The first set I received, none of the nozzles were the correct size and constantly caused under extrusion.Customer service contacted me and sent me a second set free of charge. Though when they arrived, I noticed that they were a different style than the original set. I tested all the .04 nozzles and out of 10, 6 were the right size, 3 were slightly smaller than they should be which might cause under extrusion issues and one was definitely not the right size which would cause various problems had I used it.I definitely don’t recommend these nozzles unless you have the patience and tools to double check the nozzle size of each nozzle before use.

Not only is there a weird lip on the nozzles that catches prints and ruins them, but the nozzles are not standard length and are much longer so therefore they stick out much further. Could not get a single successful print out of these. Unfortunately I did not try then until I was outside the return window.Zero stars.

Out of the entire pack NONE of them where the proper diameter. some were not even a clean hole so the material would ony partially come out.each of my tests were done 1 after the other, only printing small parts like the ender3 dog for example. I had no clogs or jams and yet 100% of them did not extrude correctly.

Nice set. Had to increase the temperature due to the Stainless Steel. Did find in the .8 a bit of the Stainless Steel coating leftover in the inside of the nozzle, was easy to pop out with a drill bit.

This is the lowest price with great quality & extremely perfect customer services.

I only use the 0.4mm nozzles and every single one in this package failed to even extrude material on an Ender3

It works very well with my Ender 3 and no issue came out during the past few days.

Bought these so that I have a harder wearing nozzle for my more abrasive filament such as glow in the dark, wood pal and carbon fibre pal and they worked a dream until I found that 20% of them did not actually have a hole, so constantly clogged my printer. Seller did offer full replacement or refund but I was happy to keep as you get so many I just checked and threw away the damaged one's.The one's left we're perfect.Note: if you didn't know already you need to change the settings in your slicer software every time you change the nozzle to a different size.

Struggled for hours to get one of these to properly print, lots of clumps and surface scraping of prints, put the old nozzle back all perfect. only reason i bought these was to print more coarse plastics like carbon fibre but they wont even print PLA. Also you get a lot for your money (quantity) so clearly they are very inexpensively made!

i tryed them nozzles for over 10 hours... loads different spools and settings. put in a genuine ender nozzle back in and made perfect parts. DONT WASTE YOUR TIME.

Work well. Needed to up temperature a bit
