Stumped by a little puzzle

[1]

It’s understandable that I was instantly seduced by the elegant black and green see-through packaging with the wooden puzzle snugly housed within. I opened the little box carefully, and had to firmly pry loose the puzzle.

There seemed to be several little wooden pieces locked in close embrace. When pulling didn’t yield any results, I put a screw driver to the task. Careful to not damage the wood, the puzzle was finally broken down into 12 wooden pieces, carved into simple and elaborate shapes. Caustically, my guest suggested the puzzle was to figure how to take it apart. I certainly had made heavy weather of it so far. For no particular reason, I’d taken a picture of the intact puzzle as soon as I’d taken it out of the box. It’s just as well I did. There seems to be no putting it back together again!
The guest had recently been to Bangkok and she’d brought me this Mini Puzzle. There is a fold out sheet that offers some sort of solution. Deciphering this proved impossible as well. Mini Puzzle is a major dilemma. I’ve twiddled the pieces for hours on end, hoping for a miraculous falling into place. This needs a cunning plan!
