I did not like the single buffer holder in the current position on the buffer. Not steady at all.
Since I was standing the buffer up for my dry box shelf I came up with these mods to stand the buffer up securely by the printer with the pulleys at the top for easy loading.
This should be additional buffer holders in the Original PRUSA MMU3 printable parts.

The author remixed this model.
The buffer holder works okay but it does not keep the buffer stable and is too tall to fit under the stepper.
I cut out the upper section between 50mm and 110mm down to 17mm to fit under stepper on the long version.
I then shortened the original by 40mm to align with the rear section of the frame.
