Jujutsu Kaisen Nobara Kugisaki Hammer

I really wanted to try making Nobara's hammer from Jujutsu Kaisen and 3d printing seemed to be the best option.
This is my first real try at designing a 3d model, so there are probably a lot of mistakes.

To save as much support as possible or if you have a small 3d printer, I suggest you use the version broken into 4 pieces.
It is designed to be assembled using 8*40mm dowels and you will need 8 of them.

You can also print it with only 2 separate pieces (the head and the handle) and assemble them with 2 dowels if you don't care about supports and have a large enough printer.
