Reverse Bodwen (rail setup only) - uses mini pneumatic clips

I will see if I can make a new X motor mount for wheel setup that can accommodate the same thing
the model for PC4_M6 needs a small 9.5~10mm ptfe tube sitting between the two pneumatic pieces (PC4_M6), also it's may be needed for carve out the end of the ptfe tube in a funnel shape to help guide the filament in case of small misalignments when you feed it.
Also It's best to get larger inner diameter ptfe tubing meant for 2.8~3mm filament ( but still 4mm outer diameter) to reduce friction. Unlike a Bowden setup this is just for guiding filament cleanly.
only place to keep smaller "normal" ptfe is between the direct driver extruder and hotend.

Just added it, filename with PC4_M6 pneumatic coupling :) printing it now to make sure it works, but if too tight or too loose don't hesitate to let me know, and I can adjust it.
Would it be possible to create a version of this that uses pneumatic couplers like the one in the Sunlu adapter? They are much easier to find here than the pneumatic clips.

Oh that was a quick design I made a while back and forgot to post it ( most of them broke, but that one lasted ) I will find it an post it a bit later
Nice! Can you share a link to the coupler you are using to attach the PTFE tube to the Sunlu Filament Dryer? Thanks!
