Indeed I do sir, I found my original sheet with the plan so bonus points for not needing to re-measure the case
Now that picture is from Rev's CMON guide, which is also good for instructions on putting the case together. My dimensions are no doubt different, but the basic idea is identical.
Everything is made using 12mm plywood.
Ok, the three large panels are 85cm long when assembled, with a 35/15/35 split. They are all 80cm wide.
The four smaller side panels are all 35cm long, 7.5cm high. The other two panels which form the top of the box when it's closed are 77.6cm long (80cm minus the thickness of the side panels) and 7.5cm high.
That gives a small amount of leeway on the board, and about 24cm of real estate on either side of the board for dugouts and turn tracks etc. So there is plenty of room to mess with the dimensions to suit your needs.
So as long as your dugouts are 7.5cm or lower the box will shut without a problem. If you put a structure on the middle panel (like my score tower), you need to be careful it will fit with whatever else is on that side of the box, so it all closes. I would have preferred the score tower on the same side as the dugouts, but then it wouldn't have been able to shut!
