About this 3D model

Inline PC4-M6 Filament Feed/Retract Coupler Inline PTFE/Bowden tube coupler, with space to push or pull filament through the PTFE tube. I use these inline with my dry boxes for retracting / loading filament. Cut sections of PTFE tube (6-8mm) and press them on the inside to avoid the filament shaving against the PC4-M6 brass. PC4-M6 Threads are included on each end. No Supports
