Reverse Bowden Adapter for Dual-Gear-Extruder
thingiverse
I modded my Ender 3 Pro to a direct drive extruder. This resulted in the filament getting fed from the top. While just guiding the filament from the top extrusion with a zip tie works, it is not the best solution. So to not have a sharp angel at the zip tie, I added the now not needed PTFE tube back in as a reverse bowden. This little guide snaps over the extruder and holds the PTFE so there is no accidental kinking of the filament. To fit the PTFE tube i drilled the hole with an 4mm drill. Should work with all dual gear extruders, but i only got this [one](https://smile.amazon.de/gp/product/B07W6SW4TN) to rest
