Any problems, suggestions, feel free to comment (I'm sure you will anyway.)
First you'll have to download and print off the PDF on an A4 sized page.
It's set up so if you print the second page on the back of the first page, the two sides of the designs line up.
Hopefully the printed out design will be fairly self explanatory, you cut all of the outside lines, and then fold all of the inside lines. It doesn't matter which way the folds are, as they will all have to bend both ways. I used a stiff card, but I'm sure paper is fine too.
YOU WILL NEED;
1 x printed out PDF file on A4 paper/card.
1 x sharp knife.
1 x paper glue
1 x cutting mat
Step 1: Folded
I made the model, and then thought to take photos later, but hopefully it's easy so far.
