As I have the Oculus' cable routed through the ceiling with pulleys, I wanted the cable to exit from top strap (centered) towards the back.

After some tinkering and tests I designed this object, better explained by just looking at the attached photos.

The zip in the back attachment is there to prevent the cable from sliding back... ugly hack I know...

Notes:

• Back black attachement is the one that comes with the rift
• Front black attachement is this one: https://www.thingiverse.com/thing:1686552

  But I guess any flexible will do.
