PTFE Coupling bracket
Description
I was having problems with my filaments twisting up, and kinking while using the Prusa MMU2. As you can see in the photos I'm not using the standard Prusa MMU2 spool holders, or the brackets that come with them to keep filament under control while it's being ejected from the MMU. I'm using the split PTFE tube setup. I originally just had the PTFE tubes hanging out behind the printer, but this allowed the filament to loop back on itself during an eject cycle, and then kink and sometimes break on the next load cycle. I found that if I taped the PTFE tube on the filament side of the cut it prevented the loop and kink from happening. I wanted to make it a more permanent fix than just using tape, plus it looks a lot better. I made this little bracket to hold a PTFE push through fitting, and then I just used some double sided tape to stick them to the walls. Since I started using them, I've had no more kinking problems with my filament. The push through PTFE fitting that I used can be found here. https://www.amazon.com/gp/product/B01IB81IHG/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1),
