I came up with a way to bring the filament to the extruder using some ptfe tubing and a couple pressfit connectors. Its basically just a holder for one end of the tube that slides on over the aluminum angle on top of the cable chain. I added some cable chain links that i modified to carry the bowden tube aloge the side of the cable chain. this allows the filament to make it to the extruder without getting bound up on the machine or worse having the filament get tugged along by the extruder causing the exrtuder to flex or wobble.
everything is up on thingiverse:
