MK4S Electronics Box cover with fan controller

Added mount for temperature based fan controller so it would turn on a fan to cool the buddy board once enclosure temp climbs.

I used this controller: https://www.amazon.com/dp/B09L1HJSG3
It comes with traces for a 2.54mm pitch connector but no actual connector. Was easy to solder on a JST-XH socket but also you can just wire it into the screw down bar (ideally with ferrules)

You'll need 3x M3 4mm SHCS (or possibly 6mm FHCS) for mounting the board

I use it with this buddy box cover:  https://www.printables.com/model/856236-mk4mk4s-xbuddybox-cover

Tips:

• Stick the NFC coil in first.
• Plug the temperature probe into the controller before installing it.
• Make sure fan and NFC connectors are fully seated before putting the cover in place.

DISCLAIMER:  I have no idea if this will interfere with the NFC coil.  I don't know enough about NFC sensitivity to EMF nor do I use the NFC.
