This is a very simple “case” that holds both the fiio A5 as well as the fiio BTR5, while both units being positioned in such a way that you have access to all the inputs, and can connect the BTR5 to the A5 using the A5s connector.
Just in case you need this very specific setup.
I'm sorry.
Would recommend printing in PETG at least, for that extra bendability on the BTR5 section.
