I've got 1up's Pacmamea (
www.1uparcade.com) plans (just the side panel actually, but the rest of the pieces are square so that's all you really need printed) printed on a bunch of 11"x17" pieces of paper that could be taped together to get the whole thing. It's a bunch, though. Probably like twenty sheets of paper, maybe more. I ended up having it printed on a big plotter at school on a single 40"x80" sheet of paper, though, which is much MUCH nicer. As soon as I'm absolutely sure that I don't need it any more I'll probably float it around here and see if anybody wants to take it off my hands for the cost of shipping. I've got the sides cut out, but I'll keep it around until my cab's pretty well finished just in case.
I'll let go of my 11x17 set any time, though, so if your interested let me know. It's not a very big cab, though. In fact it's a relatively small, classy cab, which is what I really like about it. I'm not a fan of the gargantuin monstrosities of mame cabs. Any cab is going to be monstrous enough, IMO, without going out of your way to make something extra enormous.
The 40x80 sheet won't be up for grabs for a while still.
