The file 'Customizable Easy Shelf Side Bracket 3D Printer Model' is (scad,stl) file type, size is 84.2KB.
I needed small brackets for mounting a shelf over my toilet. To avoid hitting the pipes during drilling I went for side brackets mounted on the left and right wall. Mounted on brick walls with 5 mm wall plugs (Dübel) the brackets feel really secure holding a 80 cm board. I didn't design for securing the board with screws as the board is a tight fit between the side walls. If needed it would easily possible to adapt the design for more screws into the wall or board.
I printed the brackets smaller then the board so they are nearly invisible below it.
