15 Pieces 1.0mm MK8 Extruder Nozzle with 5 Needles - Wellerly M6 MK8 3D Printer Nozzles Brass Print Head with Free Storage Box for 3D Printer Makerbot Anet A8 Creality CR-10 CR-10S S4 S5 Ender-3 5

Did not notice until today exactly 1 month after ordering that they are not 0.4mm rather 0.2mm jamming constantly now I know why.

Looks like good quality, but wanted to make a note that these will not fit the CR-10s Pro

Only about 5 passed a .4mm go / no go gauge. These are probably factory rejects. Was getting horrible stringing, and it wasnt even consistent between nozzles so that it could be tuned.

Typical of trash that comes from chyna Out of spec and poor quality

Great value for the money especially when filament can get clogged and you may have to replace cant beat the price for the quantity

They work as intended and are cheap!

I trust these products for accuracy of and the consistency of the diameter. I have Ten printers that run nearly all the time 24-7 and yes they clog but they all do so I get the best deal here.

Pefectly as described. Just remember to relevel.

These were as close to perfect as I could hope to receive. The reason why I am taking 0.1% away from a perfect 100% is I found around three ultra small pieces of brass shavings on the threads of a couple of nozzles. Ultra small shavings in the 0.1mm range and a couple in the plastic bag. The interiors were pristine.

Nozzles seem to be working well. Very good to have spares around when printing a lot.
