Reinforced sign post bracket.

I needed a way to mount a no parking sign to a post so the best way was to custom design mounting brackets to fit the size of the sign. 4 brackets were connected to a post to provide a backing area. 123D Design was used to draw the bracket, and Matter Control version 1.7.5 was used with the Cura engine to slice it. Matter Slice & Slic3r engines were used as well but the results came out better when I used Cura since ABS has major warping issues when printing large files with a lot of thin extruded surfaces. I had minimal warpage with Cura at 30% infill, and 300 resolution. I also used a no name brand cheap quality ABS which might have contributed to the warpage issue.
