Total length is 580mm. Sorry for using SI units. It is more accurate that way because the number is rounded...
Calc: (4 x 120mm) + (4 x 25mm) = 580mm; 4 x 25mm would be overlapping I mentioned in my original post...
Cheers Bob... and... sorry to be a bit of a doof here, but how much are we talking in grams?
