Little Clip perfect for the new BoboVR S3 pro, it doesn't come with it's own clip like the previews models and I made it myself, it snap perfectly in and it slide very good making open and close the headstrap, for different head size, a no issue.

no support need it, I did mine with standard BL pla and no issue with it

This is the headset model https://www.bobovr.com/collections/quest-3-accessories/products/s3-pro

enjoy your VR
