PTFE coupler for TZB MMU2S filament buffer

thingiverse

I've built the TZB MMU2S filament buffer, which demands 10 PTFE couplers with R1/8 thread. In my setup, I need to be able to rapidly connect and disconnect the five tubes, so I designed this solution where all the tubes are clamped simultaneously using one clamp. It's only necessary to use the clamp on the couplers connecting the buffer to the printer. On the other side, it's enough just to slide in the PTFE tube. Note that the male and female parts of the clamp are supposed to be printed together with the hinge assembled (it cannot be assembled or disassembled afterwards). In order to facilitate this, I have added one PrusaSlicer 3mf file with the parts assembled as well as one extra STL with the parts assembled.
