This is a adapter plate I made for my Anycubic Chiron to fit the BigTreeTech Octopus or Octopus Pro. It will fit over the 4 post but the Left hand side will need stand offs to give it more support for the board. I added holes on the top, bottom, and left hand side for the wires to fit in. This isn't a flashy design but its functional. I hope you enjoy.
