EDIT: After some feedback and inspiration from remixes I designed a version of the bottom that prints in one piece, no screws needed!
A removable drawer and bin to collect purged filament from the Centauri Carbon. It also helps seal the enclosure, and has a detent to keep the drawer from accidentally sliding out (no magnets required). This model still allows you to remove the drawer and have purged filament fall normally.
I designed this to match the design of the printer itself, and it's designed to use the same handle as the front door and top. No supports required.
I also included a second version of the bin with screw holes that can be mounted without the top part.
The author remixed this model.
I used the dimensions from the Centauri Carbon model to create the purge bin and modified the handle to fit M3 screws
