E3 Dremel Filament Holder
thingiverse
I had gotten a good deal on some "Dremel Filament" and the hole on the spool was to small to fit my Ender 3 spool holder. This should attach using the same screw hole used on the creality filament holder, on top of your Ender 3/Pro. This allows the use of the smaller filament rolls with smaller holes.
