Here is a little filament holder i designed for the Anycubic Kobra 2 neo, it should work on the Anycubic Kobra 2 and maybe Kobra 2 pro.

You will find 2 variant of the holder, depending on wich side you want the spool (Left or Right).
If you print the complete versions, you don't need to print anything else.
If you decide to use the version with the roller you will need to print the Spool holder, the "Filament holder", the "Filament roller" and the "Filament holder nut".

Weither you choose the complete version or the version with the roller you will need :

• 2 screws M4 x 12mm,
• 2 bearings 608zz (only for the version with the roller).
