Castle Grayskull

This is a remix of https://www.thingiverse.com/thing:1868554
A friend wanted me to print a Castle Grayskull for her boyfriends birthday present. I liked the original but wanted to make it more like the castle instead of a dice tower.
So, I cut the tower in half down the middle, mirrored it, joined it so I would have the turret without the 'face' on it. I then copied it four times and layered them around the main turret, I reduced the size of the main turret a little so it stands out more.
After I did that, I removed the overlapping circles inside the castle. After I printed it, I decided I wanted it to have a 'lid' so I made that from scratch too.
The lid (or STL called 'inner'), in Simplify 3D I reduced it to a scale of 99% because it would be too snug to put in full scale.
