Most monitor mounts hand or stand on your desk, but if you don't have the room for this where do you rest your headphones?
Well I saw on amazon THIS headphone mount: https://www.amazon.ca/TotalMount-Monitor-Mount-for-Headphones/dp/B083JLDPDP
The only problem I had with this was that it was over $40 after shipping, I knew I could design and print one for cheaper. The one above was my source of inspiration
Free to use, remix if you like. Designed to be used with pull tab adhesives that are very common on the back of any monitor, even curved (It is thin enough to flex over my curved monitor)
The tolerance between the two parts is 1mm total, which I have found to be a perfect fit on my P1S. let me know if I need to make changes.
