The Bambucket is a filament purge container for Bambulab printers. It is attached securly via 4 magnets(d:5mm,l:5mm). It has top lid for easy cleaning.
Just pop it back in after you are done.

I have designed this low-profile purge collector because I don't have much space behind my 3d printer and other low-profile designs either filled up fast or got jammed with the purged filament.

The magnets use a press-fit slot that has an ejector slot to it so If you want to change this mod you can recover the magnets.
