We aim to make the construction of the windturbine as easy as possible. This means a minimum of glue and screws. For the tail, we designed a piece that holds 3 aluminium rods and can be mounted on a 40mm pole. Since the rods and the PET flex a little, they will interlock because of the tension of bending the rods towards eachother:
