This morning we started to think about the design of our sphere. We plan to build it with a 3D printer. The external diameter will be 16 centimeters. After modeling the first few components with SolidWorks, we are stuck. We have to find a way to build a 3D structure which can bear the PCB, the battery and the LEDs. We found some balls which were made by assembling triangles, but is doesn’t really correspond to our project.
At this moment, we have the idea of building two concentric spheres. The internal one will carry the components : PCB and battery on the inside, the LED strips laid on the surface. The external sphere is going to provide a round shape.
Any ideas or feedbacks ?
