OpenGrid Edge Edging Surround Frame

After deciding to use the opengrid system for my walls I tried to find some finishing strips or edging for it. Couldnt find any so made my own. All my personal grids are 8x8 so that is the size I made for the borders. there are two parts to the border, the corner and the straights. I have left some tolerance for the edges and designed it for opengrid full size with corners.
