Part 4/8:
The maker quickly realized that the true complexity of the project lay within the iPhone's internals. Studying the device closely revealed various screw mounts and profiles along the chassis, elements critical for functionality. Faced with the absence of detailed drawings, he devised creative solutions to measure and map out the intricate components.
He employed a method involving scanning a shell, subsequently milling it to create 3D images at different heights. This enabled him to visualize the internal structures necessary for mounting screws and integrating components. The meticulous nature of this work led to the discovery of nuances in the design that would be integral to the finished product.
