Nothing quite so nice, I used a cigar box with holes drilled in it. The sliding wooden door made an easy battery door (believe it or not I have two of the 18,700mah 3S cells, so I can swap them out as I wired it to an XT60 opposed to the board itself), the massive space inside allowed me to place the rest in. Cut the screen panel, drilled the button and 510 holes, wired in the board with the battery then it was done. Look me 30 minutes to make. I'll post some pictures of it when I'm back home, I'm in VA with my boyfriend at the moment and that beast is not something I carry around with me.
It's a longer, thinner box with a sliding lid like this:
