Initially, various constructional solutions were outlined in close collaboration between the industrial designer and the engineers, so that the details of the construction and the production could be prepared at an early stage. Initially Guldhammer A/S would manufacture the product, but in order to reduce development time and thus the cost price 3PART proposed that subsuppliers subsequently be used. On 1 January 2002 3P supplied the designs and parts lists, and by 15 January a prototype had been developed for subsequent modification.
