Adimlab Gantry Controller Box Remix

I remixed Jon Bourgeois controller box for the white board. I updated the holes spacing for the white board to 152mm x 62mm, increased the rear cutout down by 4mm, the front cutout was reduced to only allow for the LCD cable. I moved the 1 hole for the fan bracket back by 4mm to allow for more clearance with the USB connector when the fan is installed. Cover and fan bracket can be found in the original location.
