First of all, I'd like to compliment you on the build so far... it's coming along nicely and I definitely will be following closely
Although I've been dabbling in paper modelling for years, I am still too much a beginner to even dream to trying such complicated stuff... I can't even cut rounded corners or circles properly!! lol
I have only built very simple models and even then, only those with clear definite corners and lines.
I agree with birder and WVA, I reckon the cut is on the line to the printed area. But, I'm no in any position to be giving advice!!
