The “factory default” nozzle dimensions on the Ender-3 is 0.4mm. But a number of people swap a bigger diameter to “print more rapidly”, and several swap a smaller diameter to “print finer”. I am also using the DT Swiss XD freehub body and that fits and performs beautifully. Elitewheels shopper https://ermaa008lan5.theideasblog.com/profile
