Quest 3 - BOBO VR S3pro controller holder dock

This is an enhanced version of the original controller holder, to match with the BoboVR S3 Pro (and maybe other head straps).

Changes:
* added ramps to the side, that places the head strap/quest always centered to the holder.
* added a holder in the middle to store the head strap battery.
Do I need to remove the battery?
No, it's optional, if you have 2 or want to have it removed from the quest when storing.

I recommend using 5% infill, to save filament, to me, it's strong enough using PETG.
