Base for roll

thingiverse

This design serves as a foundation for a 120mm filament roll mount suitable for any printer. Its intended purpose is to sit alongside the printer, allowing the filament to feed smoothly without movement. To maximize its effectiveness, it's recommended that you print this model with its orientation unchanged, permitting the layers to create pathways that enable smooth roll movement while coping with overhangs. Although printing without supports worked well for me in my test, I suggest you verify this approach before use.
