Step 1:
I made these papers by glueing two standard printer / copy papers together and cutting them into 30x30 cm papers.

Step 6:
Insert the silver colored box into the red box.

Step 5:
Use glue or tape on the four corners.
Repeat steps 4 and 5 on the red paper.

Step 2:
Lay the silver colored paper on top of the red paper and prefold over both papers in once.
This will make the silver square fit exactly into the red square box later.

Step 4:
Now both papers have the same prefolded pattern.
Fold the corners inwards and the edges straight upwards.

Step 3:
Prefold both halfs into three parts of the same size.
Repeat in the other direction.

Step 10:
Fold in half, into a straight angle

Step 8:
The four sticks are folded out of a4-size silver colored papers.
Fold in half.

Step 9:
Fold over these two lines.

Step 7:
The base is ready now....

Step 16:
And the lid is also ready, I actually made it stronger using a piece of cardboard. I did the same with the base of the machine.
I slided four small glass pieces from old photo frames into the base, which gives the model an extra realistic look.

Step 15:
This is an a4-size red paper. Prefold over the diagonal line, then fold over the right line.

Step 12:
The four yellow plates are also folded out of a4-size papers.
Fold the papers a little shorter over the light yellow line. Then fold them in half two times.

Step 11:
Slide the four sticks into the corners of the base

Step 14:
Done.....

Step 13:
The yellow plates are glued to the inside of the sticks, see white lines as example.

Step 21:
Prefold all eight lines into the same direction.
Then glue the right end to the left edge, see arrow.

Step 19:
Prefold in half, then fold both edges to this prefolded centerline.

Step 20:
Fold both edges to the centerline and unfold the folds of step 18 to 20 afterwards.

Step 18:
Fold over this line.

Step 17:
The kettle with lid is made out of an a4-size paper prefolded and cut into half.
Prefold over the lower line and fold over the upper line.

Step 22:
Fold this spot downwards, use the prefolded lines as help.

Step 28:
Prefold along the edge over the yellow line. Then pull the upper flap to the left and fold over the prefolded yellow line.

Step 25:
Done, this is how the bottom looks.

Step 26:
Use the size of the kettle to fold the paper for the lid into the right width.

Step 24:
Press the bottom of the kettle flat

Step 23:
Fold the other seven corners downwards.

Step 29:
Fold over these three lines.

Step 27:
Prefold over the four light yellow lines and fold over the thick yellow line afterwards.

Step 30:
Make a rabbit-ear fold.

Step 31:
Squash-fold the tip, see arrow

Step 32:
Fold the lid into a shape with eight sides of the same lenght.

Step 33:
And the kettle is also ready.

Step 35:
This is how to kettle lays on the silver strip....

Step 34:
Prefold and cut a silver colored a4-paper into half, see step 17 as example. Then glue both pieces together into a long strip. Fold this strip in half over the length 2 or 3 times.
Fold the silver strip around the kettle and glue it to the bottom of the lid. If the strip is to long, you can just cut off the useless part.
