It turns out the filter of the Roborock S7 is not the same as that of the S6. ;)

Thanks to the clean fusion 360 file of fns720 it was easy to remix this adapter. For fun I added some Roborock themed embossing. I also included a 'clean' version.

I printed the adapter with just 2 walls and no infill. It's a bit flexible but more than strong enough for the job.
