This is a ground up design for E3D-v6 'metal only' hotend mount on K8200. You can reuse the heater element and temperature sensor. Unlike other versions, this mount has two sections, locking the mount from both sides, and can be further secured with screws. I would recommend all K8200 user who are still stuck with the 0.5mm nozzle to upgrade to this. Note: you will need new longer (>30mm) m3 screws to mount this onto the extruder unit plus a 30mm 12V fan (tie supply this to the hotend supply) and 14mm M2 screws to secure the fan This is obviously a better design than the rest because it is designed by a girl... Happy Women's Day!
