Update 4: *cray cray* has designed a new mount for the *catcher*, which I like because it doesn't interfere with the concept of rotation.

Update 3:

*Deran 3d print* has designed what may be a better ring. Try printing this one if it doesn't work with the original one.

Update 2:

I wanted to make a slightly different collecting tray and connect it to the segments. I succeeded, but it was difficult to connect it to the segments. Which is actually logical, because the container brings a stiffness to the segment. Only when I warmed it up a bit, it went onto the segment with a plop. And again, I was fascinated by how flexible and satisfying it was to position.

(Sorry for all the colors, but I have to print leftover filament)

Update 1:

I rethought the attachment and designed a ring that can be attached above and below the ejector opening with the printer's screws. This makes it easy to reposition the ejector to the left or right. However, you should be careful how tight you tighten the small screws, it should be very little. It may be a good idea to additionally secure the ring with tape or use other longer screws.

The catcher is easy to click into the ring (watch the video). Maybe the catcher does not rotate properly in the ring, then I recommend simply rubbing some candle wax on the rim of the catcher, then it runs easier.
The holder is then no longer needed.

I think it's a good idea to check the slope and set it to the maximum possible to prevent waste from accumulating in the pipe

Initially:

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.
