    Micro Swiss NG™ Direct Drive Extruder for Creality CR-10 / Ender 3 Printers (Linear Rail Edition)

    Dramatically improved print quality of KP3S Pro

    I modified the adapter plate to fit on my KP3S Pro and it's printing wonderfully, huge upgrade over the stock extruder. No stringing, fantastic bridging, it basically doubled the value of my little printer and after printing a modified X axis endstop bracket, did not lose any print area! This is my 2nd NG and I love them, they make printing easier and require less tuning.

    Beautiful piece of kit

    As an owner of the first gen. direct drive M-S extruder I speak with some authority that they have taken an already good product and made it much better. I like the built-in heat sink and the angled drive motor (to shorten the filament path). It was easy to install and the supplied fan shroud finishes it off nicely.

    2nd NG, going on a E3 CoreXY conversion.

    Closest to the perfect Hot End/Extruder out there. Combine it with a CHT high flow nozzle, and it is all you will ever need.

    2nd one

    Easy to install with very nice directions. This is my second for another creality printer I bought
