Exist a little side gap between the base key and the headphones support, nothing that doesn't fix with glue. very happy with the results. I will print another one for other headphones I own. :)
The design is nice and printed well, the issue I ran into was the connection between the base and headset holder. there was way too much play, I had to glue and hold it in the correct position for a while to get it to not lean to one side.
