PTFE-Feeder Configurable

Configurable Filamentfeeder for my Printer.
Why?
The most time I printing with 2kg Spools, Black and White 

Sometimes it gives a heavy shock when the Head goes from one Side to the other.
I have 2 times lost some steps from the X-Stepper.
So i look for a solution and found it in a PTFE-tube.
I draw this Idea in FreeCAD with a big help of C4e and RalfG from the
FreeCAD forum, Thank you for this help 

You can change 2 Parameters, look at the Pictures.
Attention, the Parameter Angle (Winkel) goes max. to 179° 
and lower then 100° make no sense.
My Prototyp is 30mm long, but i think the next Test 
would be 25mm with an angle of 150°. 
The Tube is 390mm long.
