Ender 3 Sample Filament Nut

I needed something to hold sample filament on my filament holder. Looked into print sample spools but nothing struck me fancy. But I did run across a filament spool holder, linked below that had a nut on it and decided to make the brim big enough to keep the sample filament from popping off. Low and behold it works. (On a related note, yes I know the bracket for my filament holder is on backwards. Just been to lazy to turn it around)
