Batman Dark Knight sign as a shelf, if You have bigger printer You can scale it even bigger and make it real big shelf for books or anything.

This one is not enough big for books but can be used as a display of batman Iego figures or something like that.

I have uploaded two versions- with holes for nails or screws and secont without to be glued in or You can modify it for other fixings to the wall.

The first image is only illustrative, the print profile is smaller, 3.5cm thick, please read description! But if You have big enough prtinter You can print it as big as You can :)
