Magnetic headset holder!

thingiverse

This headset holder stands upright by magnets, allowing you to place it on your computer (if your case is metal) or elsewhere. The magnets used measure 15 x 10 x 3 mm. However, you can adjust the model to fit your specific needs. The holder can support at least 500g in weight, depending on the strength of your magnets and the surface they are attached to. A helpful tip: Apply a small piece of tape to the bottom of the holder to prevent it from sliding.
