I designed this two-tier filament stand that can be printed even on the Bambu Lab A1 Mini, since it’s made of two parts that easily slide together.
For a more aesthetic look, you can print it in multiple colors.

To complete the assembly, you’ll need four aluminum tubes with an outer diameter of 15 mm (inner diameter 13 mm). (Link)

For improved stability, I recommend applying a small drop of super glue where the parts connect.

This design is practical, space-saving, and easy to assemble — perfect for keeping your spools organized and your workspace tidy.
