If you are a member you can download this model for free at the link. Thanks for signing up!


Download the files and print out the parts. The first page is the bellows, this is printed on normal printer paper. The remaining three sheets should be printed onto thin card. (230 gsm / 67lb) I used coloured card to make a colourful model. You could use white, coloured or patterned card for your model.

Score along the dotted and dashed lines and cut out the holes before carefully cutting out the pieces. Paper pipes must be made as accurately as possible if they are to work properly. Take care!

Check out the YouTube video of the completed model.
