Ikea Fjallbo headset hook

Here is a pretty simple design : a hook that hold your headset on any of the 7mm holes you will find on a Fjallbo line from Ikea.

My print is made out of PLA and I set the infill to 40% to make sure to have enough strength and rigidity, It feels just right at that setting.

The design was originally made for my headset is a Bose SoundLink II, the head "arc" is a 2,5cm wide, and the holder can take up to 3cm. I believe it can be fit a lot of other headset.
