This is a remix of the side Filament Spool Holder by builditfull, made to work with the Creality CR-10S PRO.
It mounts on the side screws, and on the 2020 side-rail.
By having the spool on the side, filament guides are not necessary anymore, and the printer can work at higher speeds without creating wobble.
If there's somebody skilled that can remix this piece in a better way, please do :D
