The Ultimate Headphone Hanger
The Universal Headphone Holder / Headphone Hanger fits securely to almost any desk, table, or shelf, up to 1-5/8 inches thick. Its interchangeable attachments come in two different sizes to fit most larger audiophile type headphones. It has been over engineered with enough strength to hold belts, hoses, purses, handbags, extension cords, and more.
You will need to print two pieces, which securely lock together using a proprietary space age dovetail joint. The clamping mechanism prints fully assembled. It can be printed without support, if you want, but one side of the screw will be ugly. The tolerances are very tight, so its recommended to print at the finest layer height you can. This will ensure that it can clamp down tightly and hold fast. The more infill you use, the stronger it will be. When properly printed, this device is capable of holding large amounts of weight.
I've provided both horizontal and vertical mounting equipment, as well as several customization options including Sony, AKG, MakerBot Jewelry Hand, and Darth Vader themes. The basic attachments can be printed with little to no infill and no support. Some, like the hand, may require some support to be printed. There is also a printable 1/2 in allen wrench included, which you can use to tighten it down
I recommend personalizing the hanger with your own monogram, text, or logo before printing. You can print the two parts in the same color, or mix and match. The possibilities are endless!!
3/14/16 update - I've added another clamping mechanism (XL_headphone...) that is even bigger and stronger, for the most demanding applications. It includes built in support so that it can be printed supportlessly. You can see it in use, in the picture that says 'BAZ'
Use lots of infill for strength on the clamp part. No supports or infill is needed on most of the attachments. I printed all of mine in PLA at 0.2mm layers. The Sony one in the picture is glow-in-the-dark PLA. The AKG one is pink because that's what I had laying around.
When the screw clamping mechanism comes off the printer, it will be frozen together. Grab a couple pairs of channel locks and gently grip one on the screw head and one on the part it screws into. Gently twist until you hear a snap, and the screw should now move freely. Twist it all the way up and down a few times (using the optional allen wrench if you want) to clean out any loose debris.
I was inspired by anth92's design, but I wanted to make it stronger and adjustable. I tried out several different types of dovetail joints before I settled on this one, which can be printed without supports. You can copy it to make your own custom attachments.
