Headphone Hanger [Clamps up to 40mm]

I needed a clamping headphone hanger, with some way to secure the cable. Ideally it should be both compact and functional.

Design and exterior look of the thing hasn't changed much since its conception. I printed the thing and found the clamp section was far too flexible. I liked the design, so decided against making external geometry changes. 

To increase the strength of the clamp then, I made use of internal space. I included strategically placed and shaped voids inside the model around the clamp. All the voids do is tell the slicer to draw more perimeters inside the print. More perimeters, means more material, means more strength.

Cable management, my headphone cable is thin and annoying, so I added some fins to the cable management slots. Acting as a simple spring to hold cables in place. Top slot is for the bundled cable, bottom slot is for the loose end. (These fins would probably work better when printed in PETG, but they work fine in PLA. A little more brittle than the alternative, but I used PLA because that’s what I had, in Marble Grey.)

Printing

I've included Prusaslicer Project files which include the model files and print settings, for Prusaslicer 2.5.2 as well as project files for Prusaslicer 2.6.0 Beta2 (to make use of organic supports.)

Both the screw and Hanger print fine without support, just make sure the fins are pointing up! Two screws, 20mm and 30mm, print whichever you need.

I printed the screw at 0.15mm layer height and the Hanger at 0.2mm Layer height, but all of the included models work at 0.2mm Layer height. (Yeah, I was surprised too, the trapezoidal thread came out great both at 0.2mm and 0.15mm layer heights.)

A Note On Clamping

Plastic parts and table/desk-tops tend to have smooth, low friction surfaces. An easy and cheap way to improve stability is to add a few layers of printer paper between the clamp and the table.

I have three strips of paper about 120mm x 30mm, between the clamp and desk. 

Enjoy, Adam.
