Filament Guide/End Hoder

Originally I designed these as a filament guide, so the strand would get pulled through them while printing, but I found the hole was a little tight for that. However they work great for a place for all of your filament ends to stay while you are using a different filament.

Of course if you live somewhere humid you probably don't want your filaments open to the air like mine are (I live somewhere very dry, so I can get away with it :) ).
