I reverse engineered the filament swatches that come with the A1 mini from pictures from youtube video's.
They are an perfect fit with the “Swatch Display Board” by Bambu Lab: https://makerworld.com/en/models/14863#profileId-14645
I also made a version with PRUSAMENT, POLYMAKER,REPRAPWORLD and SUNLU on the back (printing with a smaller nozzle is recommend for these)
Special Thanks to Bryan Vines for the clear video of these and the temporary cover photo!
Check him out he's great: https://www.youtube.com/@BV3D
Enjoy!
