This is a very simple model for keeping headphones at the side of an IKEA Skådis board, requiring only minimal assembly and (likely) no glue. Might be a niche use, but it's one that I found quite useful! Watch the orientation – it's made for sticking out the left side of the Skådis board. Mirror the brace if you need it pointing to the right.
You'll need two of these pegs by @KimJanosch.
Print the arch with support to be safe (you could try printing without supports if your printer is half-decent at overhangs though), everything else can be left to defaults. Tolerances might be tight, but the print should snap together and onto the board firmly! I printed this using Bambu PLA Galaxy Green, 15% infill. The print holds my Beyerdynamic DT 770 Pro's without any issue.
