UPDATE 2023.07.10: v2 now includes a cutout of the Bambu logo which some will find more attractive and saves approx 22% filament on the Brace piece as compared to v1.

Only the Brace piece changes, all other parts remain the same.

v1 file retained for those who may prefer them.

I noticed that when closed and latched, my new AMS had a slight but clear gap between the lid and the seal in the area of the handle and a reasonable distance either side. Not great if trying to keep the filament dry. (see picture below)

The issue wasn't bad enough to warrant a return, so I designed this latch assembly.

Now there's no gap:

The assembly fits snuggly onto the front of the AMS and the rotating arms work just like the original latches to secure the lid firmly in place whilst still allowing it to be easily opened.

The height of the Brace part is crucial to allow it to fit snugly to the AMS without falling off or being too tight to fit. A few other dimensions for the other parts may need to be tweaked according to your version of the AMS or your printer tolerances, so I've included STEP files to make remixing easier for everyone.

I suggest printing in PETG or other tough filiament, as PLA will likely gradually deform over time. 

I used PRUSAMENT Urban Grey PETG, 0.2mm layer height with 0.4mm nozzle.

Print:

• Brace x 1
• Arm x 2
• Pin x 2
• Clip x 2

I hope somebody finds this useful.
