For use in adapting the Ender 3 V3 CoPrint KCM kits that are available directly from Creality for use with an Ender 5 Max. The kit sold on Creality's website does not include the standard power adapter included in KCM kits directly from CoPrint, instead using an adapter that plugs into the toolhead. The toolhead cables for these machines are not the same, but they DO use the same wiring and have the same connector, and so the adapter is compatible. 

The adapter connection to the toolhead cable is insecure and exposed when left as-is, and so I designed a coupler to hold them together and protect the exposed wiring. This uses the three screws that secure the cable to the Ender 5 Max toolhead, and will prevent any sort of damage to the cable connection from accidental tugs or pulls. 

Unfortunately, it does not appear that this will be of any use to E3V3 owners as designed. 

Side Note: If you are considering buying one of these kits to adapt for your Ender 5 Max, it also does not include the proximity sensor that it needs to level the bed. You will need to purchase one of these separately from CoPrint or make your own. 

Printing: Ensure model is oriented with screw holes facing down. 

Should print fine with .2 layer height and no supports. Shown printed with Sunlu matte HS-PETG, but any material should be appropriate.

Make sure you clean your bed with a good dish detergent before printing to avoid adhesion issues.
