This uses one rubber wheel bearing from an old vslot Ender 3 and a few strips of PTFE tubing to make a horizontal spool holder. This is pretty low friction; I suggest using it with another length of PTFE tubing to the hotend intake.

I included a wire exit hole in case someone wants to pop in a magnetic reed switch as a watchdog to ensure that the spool is still moving as the print goes on; if the spool stops moving, you have a jam or a runout situation. Seems like the most sensible place to detect that vs inline gadgets. I'll leave it to some smart person to implement this and hopefully remix and provide code. 

I included the freecad file for this so you can customize it for whatever bearing you happen to have in your junkbox and so on.
