I had problems finding suitable materials for the product, and also on the scale, as i thought the product was too small to be modeled with cardboard. I eventually solved this problem by using corrugated board, this help solved the problem, and i also use the thinner toilet paper roll for the smaller parts. I learnt that modeling with cardboard is easy and feasible for simple designs unlike what i though last time. Also I learnt that the glue gun glues things fast and its awesome!!
