Filament clip for .5 kg Monoprice reel

Couldn't find a filament clip that fit a Monoprice .5 kg reel. Found a great one for the 1 kg reel, but nothing close to what I needed. Works very well, a little loose on one of my reels, but snug on all the others. Fits a 1.75 diameter filament, but would be easy enough to enlarge the hole. Don't believe Monoprice offers any other size filament tho'.
