I built the very nice Another Filament Dry Box to feed my MMU2S on a Prusa MK3S+.  You can view my make.  (Note that the make picture was taken while testing, so I did not have all the spool baffles in place yet.)

I do not use a buffer with the MMU2S, instead I simply let the filament back up into the drybox.  Initially this caused tangles with mostly full spools, so I designed the baffle.  I printed 5 of them and put one between each spool and one on each end.  I have then stuffed my desiccant bags into the ends so there is gentle pressure on the two end baffles.

This has ALMOST entirely eliminated problems.  A completely full spool can still occasionally jam when the filament is fed back into the box, but once a layer or so is used I've had no more problems.

Sized to fit the drybox and to print on a MK3S+, could be a bit larger on a printer with a larger bed.  I've included the Fusion 360 file I used to generate it if anyone wants to remix for a larger bed printer.
