Da vinci Pro filament holder ABOVE

thingiverse

I needed an internal spool holder that would feed in forward. This will accommodate a ptfe tube through to the extruder. I created this so the roll rests on the lid, acting as a brake. I may need to apply smooth tape between the roll and lid (reduce any friction and safeguard the lid!). The lid will still open slightly. The guide hole is wide enough for the ptfe tube to pass through. I designed this with 10% infill. It feels somewhat sturdy, so I recommend at least 15% - 25% on the tube section where the roll sits. I'm unsure if it's a good idea for it to sit like this, but I'll try soon with some external filament. This requires modification. Edit: - This isn't ideal. Tried it and it's too thick. Working on a revised design.
