Headphone Mount
About
I was frustrated with keeping my headphones in my desk drawer so I decided to quickly design and print a mount I could adhere to the wall. Since designing such a mount is fairly easy, I took this opportunity to learn generative design practices in Fusion 360.
The generative design process involves a combination of modeling and FEA optimization. First, preserve geometry (green) and no-go areas (red) are modeled normally, and loading conditions are applied to the model. Then, the software adds material to join the preserve geometries together. Last, material is iteratively removed while minimizing stress concentrations in the part. Several versions are solved and I chose the design which met my conditions the best. The final design could support a theoretical load of 1kg with a safety factor of 18 according to the FEA simulation.
Since 3d printing was the most convenient manufacturing method for such a complex geometry, I decided to use my new 3d printer to make the mount. My first two prints failed due to strength issues from print orientation. To maximize strength, layers needed to be oriented along the median plane. Once printed, the mount was fasted to the wall using command strips/double-sided tape.
