Edit:

If you have trouble with the strength of the tool, I added a stronger version. If it still breaks, you should try a different filament. In my experience the bond between the layers with PLA is much stronger than PETG and the tool does not break.

Dealing with broken filament lodged in your PTFE tube can be frustrating and time-consuming.

The AMS Hub Tool offers a practical solution for Bambu Lab A1 and A1 Mini users, allowing you to detach the hub, remove the filament, and reattach it in under 10 seconds.

This tool simplifies maintenance, saving you both time and effort when addressing filament breakage issues.

There are two versions. One with a short handle (about 5cm) and one with a long handle (about 9cm) for big hands. :D

Since the handle has to withstand a lot, I recommend using six walls, even though using two walls saves some material and time.
