This is a wide filament guide that will also hold the tails of rolls of filament not in use. I designed this for my setup which is an modded AnetA8 in a custom glass encloser which has a shelf to hold up to 7 rolls of filament. I hated trying to thread the tail of filament back onto the spool every time I changed color/type. So I made a guild that will also hold the filament ends.
I made this awhile ago so I don't remember the print settings. But I did it in ABS with supports and a low infill for flexibility in the holders.
