Ender 3 Sample Filament Nut

thingiverse

I required something to grasp sample filament on my filament holder. Browsed through print sample spools but none caught my attention. However, I came across a filament spool holder linked below that featured a nut and decided to enlarge the brim sufficiently to keep the sample filament from popping off. To my surprise, it worked beautifully. (Incidentally, yes I am aware that the bracket for my filament holder is mounted backwards. Simply too lazy to turn it around)
