If you have any questions or if there is an error in the diagram, please open an issue.
I have drawn my own design in Fusion360 and published it on GitHub.
If you are interested, please have a look at this page: R2D2 Modular control unit (MCU) or better go directly to Makerworld where you can download the files via Bambu Lab.
There is also an extension for the body to combine the electronics centrally: R2-D2 Modular Body Backpack or Makerworld.
