Bambulab A1 no more PTFE problems
Refer to my device for the Bambulab A1 family that allows for easy switching between the AMS-lite and external spool(s), and gives access to the AMS-lite hub by just a quarter turn, without removing the PTFE tubes.

The original selftapping screws are 12mm long and the fixture is "light" with the original screws because the device base adds a 2mm thickness. So after 10 months of successful working and hundreds hours of printing, I decided to replace the screws to get a stronger fixture.
I did not find 14mm self tapping screws in 3mm, so I bought 3mm seltapping screws with a 16mm length on Amazon.
The small device is used to hold the screws to be cut. I used a Dremel disk to cut the 2mm in excess.
Remember to remove the small square of the AMS-lite hub by a 45 degrees turn, and to keep the spring inside the hub.
