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.
Parts List:
The Tube came from here: https://www.roboter-bausatz.de/p/1-meter-ptfe-schlauch-2-mm-x-4-mm-fuer-bowden-extruder-meterware
The Bowden quick-connector is ths model: https://www.roboter-bausatz.de/p/bowden-schnellverbinder-pc4-01-fuer-1.75mm-filament
