UPDATE: I printed and tested it, and for me it didn't do what I thought it would do, also the cutout slot doesn't guide the filament at all. I'll probably reboot this some day.
Yet another thing to put cotton in to pull the filament through. You put some canola oil or similar on the cotton and your filament gets lubed. Supposedly it prevents the hotend from jamming. Will print it later and see. This should fit on any 6mm frame. I didn't print it yet and so this is untested. I don't know if the filament will stay in the little spout I created or how it performs, so print at your own discretion.
