This lid is designed to fit my trash bin which is designed to fit the A1 Mini bed. See here on MakerWorld.
This model is designed to fit onto the build plate of the Bambu A1 Mini.
Easy to print in any material, but PLA will be sufficient.
Photos show it in Bambu Labs PLA basic black filament.
Size on the print plate is 179W x 179D x 180H (mm).
