I am looking for some one that can make a 3d cad model of a prototype I am getting 3d printed. it will be a two part prototype that will click together for assembly. One part being the casing the other part will house the components. I will provide rough dimensions that can be adjusted based on need of the designer. I am looking for someone that will also be willing to make multiple adjustments along the development of the prototypes. Please provide examples of past work.
