This was one of my first prints when I got started with 3D printing, because I wanted a way to hold a small amount of sandpaper and get some tight corners without having to switch to a second tool. I made a cardboard template that I use to cut out pieces of sandpaper and use a marker to label which type is which on the 3 I currently have. I've included the original item info below, the base design is not my work but this version of it is. Please let me know if you have any suggestions or modifications you would like to see, it's been a while since I've messed with this one and I've gotten better at design modifications since then.
Enjoy!
