Forbidden Island Interlocking Card Plate - Adjusted

This is a remix of the [fantastic interlocking card plate](http://www.thingiverse.com/thing:944716) by [KU4TP](http://www.thingiverse.com/ku4tp/about). The original design is great, but the cross pieces were not anchored at both ends. This caused a failed print when one curled up and got caught in machinery on my printer!

This remix is the same as the original, but the cross pieces have been extended so that they are anchored on both sides of the frame. This has eliminated the issue for me
