There are several ready-made projects for collecting waste filament from Bambu Lab printers, but having limited space behind the printer I designed the one that was right for me myself.

I also added a door that folds down to easily empty the container without having to remove it. In the closed position it is blocked by a simple C-shaped profile resting on the upper part. To allow this door to flip over, simply insert a paper clip (after straightening it), passing it along its entire length. Of course any material that fits the diameter of the holes can be used, you can try with a piece of filament.

In Bambu Studio I inserted the logo in relief, obviously the components can be customized as desired: material, colours, print quality, etc.
