THIS IS WHAT THE INSIDE OF YOUR HEAD LOOKS LIKE!
Oh, sorry for shouting, I just get really... "passionate" when it comes to learning.
The head part of this was a 3D scan of my friend Jack.
And then the skull was taken from some skull model that was on thingiverse.
I invite you all to make new models showing what other things look like on the inside such as: Animals, People, Plants, Buildings, Robots, anything!!
What sort of crazy cross-section models can you make??
I printed this in 2 different parts and just glued them together.
But the STL files are set up so if you have a printer with dual extruders, you could merge them and do a dual-extrusion print probably..... Although you will want to use full supports.
This thing is gonna require full supports.
Also, when I printed the skull, I flipped the skull model on its side, I recommend you do the same.
