Impossible?

Ekaterina Lukasheva

 

30 squares. 3x3 cm.

 

No glue.

 

First try.

 

Used some bits of tape to assemble it and then removed them very carefully. My guess is that if I fold it from bigger squares I should be able to assemble it without tape or something else to hold it together until the end.

 

I need to do this one again, some of the modules have some unnecessary creases.
