filament guide, sewing machine style

This is a filament guide inspired by sewing machine guides that orient and tension the thread just enough to slide it smoothly through the extruder.

It allows the spool holder to be in any position and direction, but not over the printer.

I put PTFE tape inside the eye of the guide and all around the spool holder's axle to eliminate friction.
This is an important point if you want to print yours, it won't work properly if you omit PTFE step.

On the ender 3 V2 with the left-screen mod it reduces the printer's footprint.

I fixed it in the back of the gentry profile with V-slot nuts also printed and 2corresponding screws.
