The following are under the category more of “quality of life” improvements as opposed to “must have”… that is until you have them and then lose them or run out and realize just how important they are.
In lieu of the Bambu supplied metal scraper which runs the risk of damaging your build plate I might suggest this cheap scraper from Amazon that I recently discovered and discussed in this post.
Aside from that, I might suggest printing a large poop bucket but use the one that allows you to insert magnets. This topic is one of personal preference as to whether you want side or back mount but what ever you decide, the two things I would suggest is print one that sits high midway above the shoot while also tall enough to touch the table. Then get one that is magnetically held. You will not regret it. Here’s a search term for a bunch of them up on Printables.
I also found that printing a spoiler scoop was a very handy addition to have when it’s time to clean out the bottom of your printer, which will look like a canary’s birdcage fed on a diet of filament in no time. The problem with the bottom of the printer is that it’s very square, the spoiler allows you to scoop up the junk at the bottom and pull it out of the printer with much less hassle.
