3d Printer Wiring Control

Nice clean design. Been thinking about adding another mosfet for the extruder myself. I'm printing a bumper board to mount a dual relay to for controlling the 12v supply to the board and the other to control the LED lights I just added from octopi.
 
I need to add a cover and fan - after I re-do my drawing with my brain engaged this time. My original drawing has a 92mm fan surface mounted on the cover. Unfortunately, I didn't consider the position of the X axis motor as the Z axis runs up and down. I can set it up with two 40mm fans that with clear the X motor.

How are the additional controls you mentioned performed via Octopi?

They are done via the GIOP pins on the RPi, which are connected to a relay...
