I was delighted when I made of paper the following “cube”. It was like the focus when the little thing is turned into the big one.
To cut such figures I recommend taking paper of not less density than 200 g. In this case they are steady, the thin details do not sag, all parts take the necessary plane.
When everything is cut and fold lines are marked (be sure to check if everything was done), turn the paper on the front side and fold in half the free field around the figure. Continue to fold keeping the same position (on yourself). There is nothing complicated here, just there are many parts in the figure.
