Is there a nice way to block the gaps between the poop chute and the back panel from inside the chamber?
I’m referring to the gaps at the sides and bottom, not the actual opening of the poop chute. The POV is at the front of the printer.
I have a series of dust covers that I use to prevent escaping filament but before I waste the airways answering a question you didn’t ask, can you clarify your ask with an annotated photograph of what exactly you’re trying to block? I’ll wager I already have a solution but then there are about six such solutions and they may not be what you want.
That’s why I asked. Now that I know exactly what you want I can suggest this poop chute cover. I have one installed on mine along with a whole slew of other dust covers which is why I asked for a photo.
You will want to print it out of a higher temp filament to mitigate heat related warping. I used PC but PETG will also work.
In my case I brought the model into CAD and removed the logo in order to print a nicely textured surface, a matter of personal preference.

Any particular reason? To me its kinda pointless as there is a huge big gap right next to it which goes to the same area, covers are ok if you like to dress up things but as far as practicality is concerned nah.
Dust covers serve two purposes. The first is obvious: it cuts off the path of egress for debris. This has an accumulative effect; the more you cut off, the less you have to clean. I have dust caps all over my printer.
The second purpose is thermal insulation. The fewer paths of egress, the less you have to cover when using high-temperature filaments. It should be noted that a 5°C rise in temperature can make the difference between good and bad layer adhesion.
As for the large gap next to it, I am working on a solution too. I had hoped someone else would tackle such a design challenge, but so far, nobody has. I am experimenting with two options: a brush design and a step ladder-type occluder, or a vertical iris, if you will, that will travel with the bed.
An alternative approach for that exposed slot is to create a chute that I can direct falling debris back into the chamber. I got that idea from a modification I made to my table saw for saw dust.
Let’s be candid, Bambu really did not spend a lot of time on quality-of-life enhancements for the enclosure. I suppose they figured that we, the ‘DIY-minded’ as they describe us, would come up with our own solutions anyway. But this contradicts their design philosophy of providing trouble-free printing right out of the box. I don’t mind doing maintenance, but try taking the back cover off your printer after a few months and see how much debris accumulates there. I wish they had made it easier, like adding a hinged trap door to allow access for vacuuming or dusting the bottom rear cavity.
