Step 1: What you need
You have to PRINT it, and cut it.
Note: straight lines ( _ ) are for cutting, but dotted lines (- - -) are for folding
And you also will need:
GLUE (it can be any glue for paper, but you have to be careful with the quantity. I suggest you have a little PAINTBRUSH to distribute the glue properly)
CUTTER (any model, but not rotative)
PLIERS (a little one; you can use an old depilate pliers)
Step 2: The panel
You have to glue it in a box shape, but as you can see on the pics, there is one side (marked with an "A") that's not glued. It has to be so.
Step 3: The back support
Bend thru the dotted (- - -) lines like the picture.
Then glue just ONE of the borders, and paste it to the back of the panel, where is marked.
See the pics to view where it should be pointed at!
Step 4: Body and keyboard
Notice there are some little tabs that should be glued and kept "inside" the model.
Step 5: Fitting the cabinet and the panel
It has to be precise, because other way you won't be able to fold the panel.
Step 6: It should look like this...
Now you have a Mini-paper-Moog. That doesn't make a sound. But it's nice.
