Paper Spool Plug

This is a plug designed for paper spools. These types of paper spool has high firection while turning on the spool hodler. They also grind off and leave paper residudes on the spool holder. I designed this simple plug to fit into the whole of the paper spool and provide a smoother turning surface. The paper spool holes usually have variations even among the same brand. So to be safe, it's best to measure the hole size and scale accordingly.
