Base mount to DuetWifi control board.
I also included a Fan mount (40mm fan).
The fan porpouse is to cool the stepper drivers, by blowing air below and above the DuetWifi board. (Exactly as recomended by DuetWiki)
Please read more about cooling the board, in this link:
The base mount is peforated in holes in diameter of 3[mm].
This enables to connect various things to the board mount, and saves print time.
I added a version without the perforation, for easier printing.
