Da Vinci 1.0 External Filament Feeder

I loaded my Da Vinci 1.0A printers with the Repetier firmware so that I can use third party filaments. I needed something to keep the filaments from jamming in the edges of the lid. I created this feeder part to snap into the hole on the back of the printer. It is shaped such that it should print without supports and be a "click in" fit that is secure but removable.

The holes should be 4mm which would allow for PTFE tubing to fit? I haven't tried that yet. You can also just feed the filament through the empty holes which is working for me.

You may need a brim or raft as there is not much of the model touching the bed.
