About this model

Remix of another bowden coupler that I had some issues with. This retains the same coupler but splits the nuts into separate print files (print two of them - both ends use the same nut) and adjusted the nut to be easier to print (at least on my printer). Very handy for coupling two PTFE tubes together. The center of the coupler may need a quick drill once done to make sure filament fits through as needed.
