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

These work ok, but I wish the OD of the tips was a LOT smaller. The detail B image that theyve posted in the description shows an an OD of .6mm. The image Im including is typical of the 0.4mm tips that I received, where the OD appears more like 1.0 - 1.2. (Tolerances, schmolerances, right?) Like I say - they work, but theres a lot more area than necessary up there, which can start to smear, leave drag marks, etc. The ones Im currently printing with are still new and work well enough. Im curious to see how they age.

Does not fit the Monoprice Maker Select 3D Printer .

Bought these to replace the original nozzle on my Wanhao Duplicator i3 that had started having problems due to printing some really abrasive materials. These fit just fine and my prints are improved, plus I have enough extras to last me for the next century.

These worked great as replacement nozzles for the Geeetech a10m. These nozzles went on easy and worked flawlessly.

As expected

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.

Let me say that I wrote a review and submitted it recently but upon looking at my printer perhaps was a bit harsh on Aokins nozzles. They are OK but not great. The reason I say this is that the hole drilled where you insert your tubing is a tad large. This leaves a very slight air gap between your PTFE or Capricorn tube, and this would mean the heat transfer is not as good as it could be. One nozzle I inspected had a defect where you could see light coming through two holes. Not a big deal considering how many you get for the price. However they could improve just by changing drill bits and making an ever slightly smaller hole for a more snug fit.

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

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.

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.
