I was wet sanding a mode and I got tired of my finger getting wet and numb. I made this to hold my sand paper in an ergonomic handle. Has a flat side for flat services and a round side for working around curved edges. I printed mine vertically with 20% infill. Its really strong, so no worries!Made this in Sketchup. Slide the sandpaper into to the top of the tool. Any extra hanging out can be rolled onto the handle after the paper has lost some of its grit due to use.
