Physical adapter to connect to a 3D printer extruder

I just received Dicov3ry today. It is looking great and can’t wait to try it on my printer.
However, I don’t seem to find any adapter in the delivery. I thought there should be one which I can just mount it to my 3D printer extruder. At least with your adapter, I could do more modification if it doesn’t fit exactly.
Please advise.
Cheers David

Hey there David! What sort of 3D Printer do you have?
