Dual Audio Extension Enclosure

My new headphones came with short cables, so I routed two extension cables from the back of the PC to the desk. To keep them tidy and easy to plug into, I sketched up this compact case to hold the plugs together.

The case is made for a specific cable from Amazon which was cheap and came in a pack of two:

I included a diagram of the measurements for the plug if you want to check for compatibility.

The top and bottom halves of the case are secured together with a M3x8 bolt.

Also included are dual cable clips for 3.5mm cables.
