Ender 3 v2 Filament guide

Filament guide for Ender 3 v2, no roller or bearing needed, just 4 mm PTFE tubing

I had a filament stick between the wheel and the frame of the original. Why invent the wheel, if you've got PTFE tubing.

This filmanet guide also makes it very easy to thread the new filament if the printer is in an enclosure, as the PTFE tube goes almost to the filament hole in the extruder.
