Designing the core - Part 2

Having decided that the core of our device will need to be a cube rather than a cross we realised that it would be quite challenging to build the original Rubik's cube around the core as it has no room inside it, as shown in the image below.

Instead I suggested we use Rubik's Void (at least for the prototype) which has a lot of room inside it meaning that we wouldn't have to worry about building the cube. The image below shows the insides of Rubik's Void (left) and Rubik's Cube (right). Clearly Rubik's Void has a lot of free space inside it.

Now that we are using the Rubik's void instead of the original Rubik's cube, I further suggested that our core should be spherical instead of cuboid. The reasoning behind this is that the inside of the Rubik's void is spherical, so having a spherical core would give us more space which is a big concern for us as we have 5 encoders each with 8 wires to fit inside the core. The idea came from watching the following video:
