MK10 M7 Nozzle for 3D Printer, 20PCS Brass Extruder Head Hotend Nozzles 0.4mm, fit 1.75mm D4/I3

As expected

Replacement for a Micro Swiss all metal hot end on a Monoprice Maker Selece V2, works absolutely perfectly. Screw in hand tight, heat up, tighten again. PID Tune. Level bed. Print! Now I just need to print a case for them all, they do come loose.

They work

I purchase the 18 pack of nozzles and only 17 arrived. I am missing a 0.6mm nozzle.

It does the job as advertised.

There are ok replacements. I had one that had a burr so the plastic was coming out all curled. I always do a purge of the nozzle right before printing and these are up to the task.

Missing parts, others seem to be the quantity described. plan on printing with these to see how it goes.

Ive only used the 0.4mm nozzles so far. They are clean and were a vast improvement over the OG nozzles I had in my Qidi Tech 1, but that shouldnt be a surprise. My only real complain is that the sizes arent etched in as well on all of them, making them hard to read without just the right lighting. That said... and it likely still goes without saying, these are cheap, so its really silly to not have extras on hand so youre not printing with janky nozzles. Frankly, its even likely worth it to use these for rough materials (glow in the dark, wood/fibre/metal filled??) knowing they wont last. If I experience any issues after playing with the other sizes, Ill update this review.

These units were a very good buy, and work quite well

Smooth nozzles, no problems.
