Geeetech M & T Series Bowden Coupler

thingiverse

I needed a replacement PC4 Coupler for my Geeetech A20M's extruder but couldn't get one delivered on time, so I decided to take matters into my own hands and print one off myself. However, things didn't go as smoothly as planned when I tried printing the M6 thread - it just wouldn't cooperate with me. So, I had to rethink the design and scrap the original plan of printing a thread that incorporated the two internal extruder parts altogether. Instead, I went back to the drawing board and came up with an updated design that not only eliminated the need for a separate thread but also made the overall structure stronger and more robust.
