When I received the A1 Mini, it came with a Box of Swatches containing all the colors offered by Bambu. I appreciated the small footprint of these swatches but couldn't find a model that was compact and allowed for adding more swatches, so I decided to create my own.
This model can accommodate up to 100 swatches, which should be more than enough. If not, I'll provide the files so they can be modified.
To assemble, you'll need 6 M3 x 30 screws. Additionally, if you choose to print the optional laser-cut window, you'll need to laser cut the .dfx file using 3mm plexiglass.
