E3D Mount for Rostock mini v4

I needed to print flexible plastic, but it was bent and sticks directly after an output from a PTFE tube. Therefore I drilled the heat sink E3D v5 on through, diameter of Ф mm that the tube passed through the heat sink as it is possible closer to a hot zone. A pneumatic fitting not really is pleasant to me therefore I used M4 nut, for fixing of the pipe PTFE. Now I can print flexible plastic.
