Monster Mouth Headphone Holder- plus audio jack

thingiverse

I don't use headphones with 1/4 inch phono jacks, but I do use a computer that sits in an awkward position for plugging headphones in and out. With a cheap audio extender (on sale for USD 1.99 at Aldi) I modified philbarrenger's design to not only hold the headphones, but also hold the adapter socket. The audio adapter has a barrel that is about 8.5mm in diameter, with a cable that is 3.4mm in diameter with some compliance. I bored a 10mm hole in place of the 1/4 inch phono 'eye' then created a pressure fit clip that keeps the socket fixed in place. Figuring out how much interference was necessary was quite iterative- three diameters of clip (5.0 mm, 5.1mm and 5.2mm) are included- print them all and use the one that works best for you. the file headphone_socket.stl is for testing purposes only- it just has a 10mm hole bored through it as a test-bed to convince myself the idea would work before committing to the long monster mouth print. Also included for the brave of heart is the FreeCAD source for the clip if the dimensions need to be radically altered. The file structure could stand some improvement as it is a little tricky to modify the size without breaking dependencies.
