V4: Version 4 added a countersink hole for mounting with drywall screws.
V3: Version 3 was created based on a comment from MakerMucilli: Add a second screw hole below the support to prevent it from swaying.
V2: Version 2 wouldn't require supports and the end detail looks a little more refined. When I need another one, I'll print v2 instead of v1.
This was made to hold a pair of Bose QC 15 headphones. I inspired by the headphone holder by polxuriach, but I modeled this from the ground up for the Bose QC 15. I used more fillets so that the design would suit my tastes. I also got rid of the open triangle in the lower gusset because I didn't like the look of it. While I added a screw hole for permanent mounting, the double sided tape has been adequate.
Version 1 required supports. Version 2 wouldn't require supports. I'd recommend printing version 2.
