Hinge Support for "Rugged Case"

I wanted to print the bottom of the box parallel to the bed, so that I could do some color change effects on the bottom surface, but I found that the hinges would easily snap along the layer lines. I created this little plate to be printed parallel to the bed, so that they would have strong layer lines and can be glued to the hinges. 

Instead of m3 bolts for the hinges, I used little pieces of bras rod and so these do double duty of holding those rods in.
