This is a lid for the Bambu poop bucket by @EnricoPulvirenti. My cat has a particular taste for filament so I wanted something to prevent her from grabbing the poop from the bucket.
The lid features a small, Bambu-shaped window to know when it's time to empty the bucket.
There are two versions of the lid: one that sits tight on the bucket, but needs some support, and one that's a bit looser around the bottom, but can be printed without supports.
I would strongly recommend printing it with a brim, as the front part might separate from the print bed otherwise!
