A small clip that can be attached to things using holes that filaments can go through. I would recommend using TPU but other filaments can work. For the folder i did i drilled 4 holes in it looped the TPU though the holes then used a hot glue gun to rivet it in place.(pressing the end against the hot surface to make it mushroom) Just for good measure i added super glue to make it extra durable. at the end of the day it doesn't matter how you keep it attached as long as it works for you.
