Gear skull

I saw a cool fidget cube some years ago that was made entirely of interlocking gears.

I modelled a functional, assemblable and printable version of it then to the best of my knowlege at the time.

Then I thought;
“that’s pretty cool and all. But you know what’s cooler than cubes?.. Skulls!”

So I found what I suspect is a ct-scan of a skull. I did a lot of cleanup on it, then I positioned it and intersected it with my model of the gear cube toy.
Maybe a bit sub optimal for printing, I have learned a lot since then. Still I think the result turned out pretty cool.

I don’t know who invented the original gear cube, but there’s a link to an example of one below.
I’m not sure who's the skull belongs to either, but I’m grateful to said stranger and to the internet. And in the very unlikely event that the cranial owner reads this.

I am impressed by your sinuses.
