Modular Sandpaper holder (block) system, Large size

This is the second in a series of sandpaper holders. This is the Large size that is designed to hold a piece of sandpaper that is 9"x3.6" (approximately 228.6 mm by 92 mm). The top can either be the larger top that is included with this print OR two of the tops from the Medium size holder (I would use a blank top and the top that corresponds to the grit you have loaded). The screws are compatible with both sizes.
