• Cut 4 sections of about twenty centimeters in the cleat. Position them at the 4 corners of the small planks cut above (the 11/13 cm) and screw them in place. On the other side position the other board and screw it in the same way. We thus obtain a parallelepiped of dimensions 11/13/20 which will be used to thermoform the plastic bottle (see photo).
