E3D embedded bowden clutch

This coupling makes it possible to make a Bowden coupling in a simple and effective way. The coupling is compatible with E3D v6 1.75mm hotends and accepts PTFE tubing with an outer diameter of 4mm. The Bowden coupling can also be mounted in, for example, aluminium or printed objects. A hole with a diameter of 8mm and 6mm deep is suitable for mounting the brass coupling.
