This is a remix of Bambu AMS Feeder Protector / Adapter by OurAngryBadger which in turn is a remix of Bambu AMS Feeder PFTE Adapter by ktothestank. Bigly thanks to them for their design work.
The purpose of this is to clip on to the top of your Bambu AMS Feeder Tubes, to protect it from wear from abrasive filaments (glow, carbon fiber, silk, wood fill, etc.).
What's new in this remix:
The example in the photo I printed with clear filament (red inset) so the AMS feeder LED makes it glow.
Instructions and recommendations are well stated in the original so I won't restate them here. The only thing I did different was to make the tube inserts half the length originally suggested (0.5 inch versus a full inch).
The author remixed this model.
