Do some 3D Modelling

Dear 3d Designer, We have a different type of box that represents our products (not exactly squared), the same type of box comes in a lot of different sizes. We use BoxShot3D (the program) to render 3d boxes but for this new type that we have now we need to import a new 3d Model (box type) to the program. We have up to now, created one but it is not possible to be resized and add the pictures properly on it. (see screen shoot) Below you will find the: 3d Model in .3ds the .ai file with the Bleeds of the box the screen shoot with the problematic box all box sides needed and the rendering program for mac with its serial. (if you dont use mac please download it for windows.) We will need from you to create a 3D model that can be imported in BoxShot3D and be fully customisable as size and pictures. The second thought, if resizing the 3D Model in BoxShot3D is not possible, is to create multiple 3D models on all sizes of boxes in order to just add the picture sides. The box sixes are as follows: With x Hight x Depth 11,2 x 22,3 x 2 cm 9,8 x 13,5 x 2 cm 8,5 x 9,5 x 8,5 cm 10,5 x 21,3 x 2 cm 12,3 x 12 x 4,4 cm 9 x 8,7 x2,2 cm 13,6 x 8,8 x3,6 cm 7,6 x 4,6 x 5,6 cm 6,5 x 7,4 x 6,5 cm 18 x 21,7 x 5,5 cm PS. The program: BoxShot3D is just a Bucked up version and must be deleted immediately after use.
