Modular Sandpaper Holder

This is a design to help organize and store 5 inch sanding disks in your workshop.The grooves are cut with a standard table saw blade width. Depth of the groove should be slightly deeper then 1/8th of an inch. I recommend the spacing of the grooves to be 1 inch apart. One could go even further and do half inch. Pictured is 2 inches and doesn't offer a huge range of flexibility. Cut the grooves first on one sheet before ripping them for the wall. This way it aligns to all three pieces of the wall
