Robo3D R2 Hanging Spool Holder

The Robo3D R2 is not compatible with the old generation filament from Robo3D. Other spool holders are free standing and occupy table space unlike the actual built-in ones designed in the R2. This accessory utilizes the top built-in spool holder as a hook and allows the filament to be placed in a similar position where it would be if using the bottom built-in spool holder.
