Summary

I got tired of my Logitech G733 volume changing while resting my head against the back of my chair, so I made this "bumper". You can still easily adjust the volume, but prevents the chair from doing it for you.

I used double sided foam tape in the rectangular pockets to attach it to the headphones. I printed this in brown so it would show up well in the pictures. I printed the final one with my resin printer, which provides a very smooth part.
