You know the staples in large cardboard boxes. I'd always had a handful around (talking since the 70's) which I would bend into scrapers for the inside of small holes or pipes. Could bend them to what ever shape I needed. I've even sharpened them to have more of a chisel or point. Problem was they hurt your fingers with any amount of pressure. Thought I would create a handle. Just have to bend them to fit the block - self tightened and will hold in place because of the bends. A hole in the body to hang if you choose and offers a little more grip. Print course as you like as it aids in grip. Use the slots to bend the staples straight or bent where needed.
