Stock CR6-SE hot end? So you have to heat up, get the right socket for the nozzle, hold the heater block, be careful with a hot nozzle coming out and then reinstall the new nozzle with the correct torque, correct? Oh all while be careful not to break the strain gauge. All that's fine BUT Revo is easier, room temp, unscrew nozzle with your hand and hand tighten the new nozzle back in, donE. For a printer with either a V6 or M12 thread it makes sense. I printed a new mount for my Prusa for the Micro and it was great to use. But I'm not selling them and you do what works/makes sense for you.
