I present to you a headphone stand shaped like a treble clef.
I recommend printing the base with a minimum of 3 perimeters and 30% infill for stability.
For the treble clef I recommend printing with a minimum of 3 perimeters, infill is optional, as demonstrated in the photos of the glow in the dark one I made which has zero % infill. If you choose to do the same just make sure you print yours with at least 5 top and bottom layers and a minimum of 3 perimeters.
NO SUPPORTS required, files are in the correct orientation for printing. The treble clef is the largest part at 230mm, which should fit most 3d printers diagonally.
