Ender 3 Spool Filament Feed Adapter

I use a DryBox for my PETG filament and feed it directly from the box. Problem was that the box is located right beside the printer while the runout sensor sits on top and wants to be fed from above. This little helper fits into the original spool holder and fixes a PTFE tube to guide the filament from below to the runout sensor above.

The main holder is cut into two pieces to help printing without support. You need a PC4-M10 pneumatic connector and a piece of bowden tube.

Printed in PLA, 25% infill, 3 walls and no support
