Da vinci Pro filament holder ABOVE

thingiverse

I wanted an external spool holder that would feed in reverse. This will fit a ptfe tube through to extruder. I made this so the roll rides on the lid acting as a clutch. May need to put smooth tape between roll and lid (reduce any friction and protect the lid !!). Lid will still open a bit. Guide hole is wide enough for ptfe tube to go through. I made this with 10% infill. It feels a bit light, so I would suggest 15% - 25% atleast on the tube section that the roll sits on) Not sure if its a good idea for it to sit like this but I will try soon with some external filament. Needs work. Edit: - Not very good. tried it and its too thin. Working on a new design
