Description

I keep my Sennheiser Momentum 4 headphones hanging on the side of my desk, and I wanted to replicate the automatic standby behaviour of the official case that puts the headphones to sleep as soon as you store them using a magnet.

To do that, I modelled a small cradle that mounts on the wall beneath the headphones, with a magnet placed in the exact same position as the one in the official case.

This is just a first prototype, but it worked well enough that I wanted to share it. Hopefully it's useful to others and I'd also love any feedback on how to improve the design, as I'm still very much a beginner with 3D CAD.

Few notes:

I don't know if the magnet orientation matters, but to be safe I checked the one in the case and matched it. I originally planned to use two magnets, but it works perfectly with just one, as shown.

Bill of Materials:

  • 1× magnet, 20×10×1mm
  • 2× Phillips wood screws, 4×20mm
  • Two component epoxy glue

P.S. the two-tone look was... not intentional 😅 but I didn't know I was so low on black PLA. It looks cool though.
