Knowing that our 19 tetrahedron modules weighed just under 3 kilos, we needed to find out how much weight our final packaging with all the extras will add to this total. The box, instructional drawings and the empty felt fold out case weighed a whole 800grams, while we estimated that the pair of scissors, 20metres of cord, packs of cable ties and split pins, picture screws and cardboard suspension discs would weigh no more than a kilo. Therefore, our final kitset design would approximately weigh no more than 5 kilos – well within the total weight restriction of 10 kilos! Whoohooo!!!!
