CR-10 Extruder Coupling

Replaces the PC4-M6 Pneumatic Fitting Push to Connect, which always tended to loosen the Bowden tube.
With this part the Bowden tube now holds bombproof. The M6 thread should not be tightened too much. The nut for the Bowden hose can be tightened to provide a secure hold. Use a second open-end wrench to hold it in place!

05.04.2019: bowden_fitting_m6-101,5p-adapted.stl added - M6 thread is 101,5% thicker for better hold.
M6-distance.stl added in case the tension of the Bowden tube always loosens the M6 connection by itself.

In case the part breaks off again and again at the m6 thread:
I have now added the file "CR-10 Extruder Coupling.stl". This has to be fixed with a cut off Nozzle Throat (including inner Teflon). This holds now bomb-proof and there is no more breaking!
