I'll post them when I get home. The measurements were figured out a while ago. The thread is still probably hereif you do a search. I think guntakela found it out along with kurtyboy.
According to scaling work done by kurtyboy of the RPF, the large box dimensions are:
Box:
Width: 82mm
Height: 54mm
Depth: 26mm
Lid:
Width: 85mm
Height: 56mm
Depth: 5mm
I haven't had any luck finding the original thread on this forum. I remember that both Kurtyboy and GuntahKela did a lot of scaling work. I think the thread eventually resulted in bandolier boxes being made. I ordered a set.
