Delta / Kossel 360° filament guide

This is a universal filament guide that can be used to guide the filament string to the extruder stepper motor.

It can be simply attached to the extruded rod (7mm groove) with an M4 bolt.
Attach it anyhere needed. The ball head AND the holding ring are both movable 360°.
Use multiple things to maintain sweet filament guiding all the way from the roll to the feeder.

I included the blender file, so feel free to tweak it and maybe add something cool like an included filament filter or so
