Sandpaper gridfinity stackable - 6 inch / 150 mm

Hi, Here's a 6" or 150mm stackable gridfinity box 4x4 model and I've added different grit labels for your printing convenience. You can easily edit the grit in bambu studio if you'd like. I'm a novice designer and new to 3D printing and designing so any recommendations or suggestions are welcome. Here's the link to the 5 inch or 120 / 125 mm model: https://makerworld.com/en/models/2404156-sandpaper-gridfinity-stackable-5-inch-120-125-mm#profileId-2635330
