Filament Feeder for MPMD Top Spool

I designed a top mount for the filament spool and then I needed a way to feed the filament into the extruder without it getting caught or snagged or anything. With a little extra PTFE I put this together relatively quickly.

Be sure to check out my other object, the top spool mount.

As a note, this is designed for standard 2mm interior, 4mm exterior PTFE. You'll need ab out 5-6 inches of it for this. It can be mounted with the same M3 screws tha
