Paper Puzzle Cube

This is a kind of puzzle cube. I made it to see what I could do with the use of really normal stuff. They are all kind of shapes that fit in the box as shown on the picture. I gave it as a present for  a gift exchange.

Like I said, I wanted to see what I could do with stuff:
- coloured paper. ( I used two-colour origami paper.)
- something between paper and cardboard( too thin to be real cardboard, too thick for paper.)
- seetrough plastic bag.
- glue.
- scissors.
- ruler.

Before we're gonna make the shapes, we want to know what shapes to make.
I made sure all the shapes I used were easy enough to make out of paper

NOTE: the black square is an open spot, not a shape.

Now take your ruler and draw these shapes!
Every square is 1 by 1 cm.

Cut out all the shapes you just drew.

Fold the shapes and glue it all together.

Now we just have to make the box to put the shapes in...
Make a cube from 4,5 by 4,5 cm. Draw a square 0,5 cm from the edge. Cut the square out and replace them by a piece of plastic bag.
Fold the cube and glue it together, leaving one side open.

Congratulations! You have made your very own special unique puzzel cube. But, do you know how to solve it?
