Stop the Rattle, Block the Dust/Moisture: The Essential AMS Hub Protector!
I designed the AMS Filament Hub Plug after noticing a frustrating trend with PETG prints. If the A1 sat idle for even a day, I would hear "popping" and see bubbles during the initial calibration lines. This moisture ingress into the PTFE tubes was ruining the most critical first steps of my prints. While other plugs exist, I found they either didn't match the sleek A1 aesthetic or relied on thin, fragile overhangs for their "slide-on" functionality that didn't print well.
Whether you are looking to protect your filament from humidity, just want to eliminate that annoying toolhead rattle or just to have a cleaner look, this plug will solve your issues while looking like it came with your Bambu Lab printer.
