I found this in a drawer, think I made it a year ago. It looked interesting so I took it apart, turns out it's made of 6 units each consisting of 2 sheets. The units are surprisingly simple and the assembly is straightforward, only part I struggle with is inserting the last piece. I wouldn't suggest using squares smaller than 9cm if you're inexperienced.
Make a waterbomb base and a bird base
Insert waterbomb base inside the bird base (evenly distribute the inner flaps)
Fold the corners in
spread out the corners, this is the top view
Just five more and done :)
If anyone knows what this model is called help is appreciated.
Thanks for checking out my post and maybe try folding it ^^
