This a Combination lock using the glyphs of the Radiant Orders from Stormlight Archive as the the code.  You may set any code you like.  You can easily disassemble it and choose a new code when you reassemble it.  There are options for both with or without an AMS.  The original design is here:  https://www.thingiverse.com/thing:586169  There are instructions on that page, but I have also written some instructions.

Note:  You do NOT need to print every plate.  The extra plates are to provide options, primarily for AMS or not.

This is suitable for any Bambu printer including A1 Mini.  The original model provided blank code wheels I have remixed to use the Radiant Order Glyphs as the code.  I have provided both embossed and debossed options.
