Phone mount compatible with Xbox one battery cover from this design [https://makerworld.com/en/models/939568-xbox-series-x-s-controller-phone-mount?from=search#profileId-905032](https://makerworld.com/en/models/939568-xbox-series-x-s-controller-phone-mount?from=search#profileId-905032)

It uses a hidden rubber band to clamp the phone in place. Works for phones with a max thickness of 12mm.

I have used it a lot and it works perfectly.

The optional extension joint places the phone higher up, improving balance (in my opinion) and allows the mount to fold compact.

The extension joint requires one additional M5x25 bolt and M5 nut (so 2 total of each with the battery cover).

Used a 2.5mm elastic cord for the rubber band.

Need to print the battery case from the other design.
