Filament Guide/End Hoder

thingiverse

I designed these as filament guides, pulling the strand through them while printing, but I found the hole was a bit too tight for that purpose. They work perfectly well however, as a holder for all your filament ends when switching to a different material. Of course, if you reside in a humid climate, it's best not to leave your filaments exposed to the air like mine are - I live in a very dry area, so I can afford to do that.
