I have a laser jet...so I suppose I could just download these and run over to Office Max right? Have them printed out on some reasonable cardstock? Something tells me these would be perfect for my 1/200 Robotech game...hmm...at least cheap stand-ins until I get proper terrain built up.
Well, 10mm is 1/200 if I'm not mistaken.
And yes, as mentioned before, go for 200 g/sqm.
It might help to put a film on the printouts using some artists medium to protect it but also to have less problems of cracking when folding the paper.
