A CAD Model was to be designed according to given Autocad file that was not fit for 3d printing as the model was not water tight. The model was scaled down to the desired size and was exported as a reference for 3D CAD remodeling. The whole model was reproduced and was divided into three parts because of the limitation of the printing workspace. The printed parts were then assembled together and the final printed result is shown in the picture on the right!
