[Q] OPO Origami dock? topic

Hi

Got my OPO from an online store in Malaysia (I'm from the Philippines). It comes with this extra package

I've watched a lot of OPO unboxing but I haven't seen this before


At the back


Inside is this thingymajig. I'm pretty sure this is some sort of a dock or something


Rear view


Tried putting it together. With all my best efforts, I've failed.


Only got this far. I dunno how to build the back part.


I tried searching for it on the interwebz but to no success.
Can anyone please point me out to a tutorial on how to build this?

Extra info: My OPO doesn't come with the Cyanogenmod logo at the back (dunno if this is a good thing). And it's got ColorOS bundled (Now using temasek's).

TIA!!
