RAMPS-FD 80 mm Fan Mount

RAMPS-FD 80 mm Fan Mount.

It works ok.

Use 3mm hex screws that are long enough to go all the way through the fan, and the boards.
Right now only one screw has a nut. The other screws will touch the solder joints on the board if I attach the nuts. I think I will have to design clips to replace the nuts, or just get nylon nuts.
