Prusa Core One PTFE Bowden Tube Connector Mod threaded (PC4-M10)

Update:
I added a M10x1 version besides the M10x1.5 version as many bowden couplers have the finer M10x1 thread.

I liked @arcuslinus_110727 mod of the right Core One Handle, but the PC4-M10 bowden coupler was too hard to get in.
Thus i modified that part of Linus' model and added a M10 thread with 0.1mm clearance to the model.

the small bowden piece between the coupler and the filament sensor should have a length of approx 28mm.
 
I suggest to insert the connector once before installation, to free the threads. A tiny drop of lubrication may also help if the threads are still too tight.

This handle goes well with my top filament guide

Added a proper M10 thread with 0.1mm clearance to @arcuslinus_110727 mod.
