PTFE "Y" Connector (PC4-M5)

And yet, another PTFE "Y" connector with a clip. This is my version of the "Y" connector to connect the PTFE tubes from AMS and the external coil to the bamboo lab A1/A1 mini. I tried several "Y" connectors to keep the AMS and outer coil mounted on my Bambu Lab A1. However, none of the existing connectors satisfied my need. The connector that I liked the most, because it was small and did not have pressure copers for the PTFE tube, easily jumped out of the connections. One solution would be, perhaps, to glue the tubes to the "Y" piece, but this brought other assembly and maintenance problems. The existing "Y" with PC4 type pressure spring handlers are designed for the PC4-M6 and PC4-M10. As I currently have several PC4-M5s, I decided to design my own connector. The PC4-M5 are slightly smaller than the M6 and M10, but offer a tight and precise connection for 1.75mm filaments by having a 2mm inner passage. The filament passage path was executed with low angles and with a large radius cur
