I find that the poop catchers are all fantastic, but somehow too static. I thought about how to change that and this is the result. You can put the exhaust on both sides of the Bambu lab printer. Or wherever you feel like. You can choose the ejection direction yourself. Whether to the left, right, or rear, does not matter. Only upwards makes no sense, unless you connect a vacuum cleaner :-)
It works amazingly well (at least for me) and takes little space. You can customize the length and you can also put it on or in a box. The external filament roll also still has enough space.
I printed it with PETG because it's only 2 layers wide and I wanted flexibility so it wouldn't break when you put it together. It is important to position the opening of the catcher and holder well at the exit of the printer. I used double-sided tape, but the best tape is special mirror tape (I don't know the correct name for this tape, but it is used to stick mirrors to the wall).

You will need a raft or brim when printing the segment and the catcher. Print it like on the 3d picture.

The idea is not yet finished, so I make it available to the community with step files to play. Maybe there will be more ideas. Especially the holder seems to me to have potential for improvement.
I wish all who deal with it a lot of fun and I'm happy about every make.
