I am the only person I know of that has designed a OW box around being CNC cut from a block, but I was planning on using plastic.
here I flipped it. In the previous picture the space under the ESC’s heatsink could have had some kind of thermal coupling to outside the case. Now the lid would need to be at least partially metal.
What do you mean this is my build thread. 
JK I can make one for my progress but I am trying to figure everything out that relates to the FOCer and the ideal configuration for upgrading a Funking wheel, or at least what to try first.
Right now I am trying to figure out if @shaman planned for this thing to fit in so perfectly or it was just magic.
