What buyers say about CCTREE 10pcs MK8 Extruder Nozzle for 3D Printer
I have been using these for a couple of months now and I have to say that they are pretty good at what they do and are easy to clean.
It works.
This is a nice set, but you will want more than 0.4s., the 0.2 allows great detail, and the 1.0 is wonderful for large fast prints.
Common Questions
Will they work with the Ender-3 Printer?
The ender 3 uses the same hotend as the ender 2 and cr10 so you will be fine.
Is it possible for this to fit with the Anet A8?
I don't have an Anet A8 but a Sunhokey Prusa Clone and the thread pitch for the extruders are standard, so I'm sure it will.
Do you need to rely on the bag to keep organized or are the nozzles marked in any way?
I received only bags and tags, and I'm not happy that the previous answer said they were.
Will this work with a wanhao i3 printer?
You should check this link for Wanao I3 use of the MK10 nozzle.
Will they work with Sindoh 3dwox?
Boss, The truth is not a clue, I have never heard of a Sindoh.
