I thought a Ring would be a cool remix for the skull, Resize as necessary, prints without supports. I wanted this to be wearable, so I did not use the lower jaw for the bottom of the ring as it felt very uncomfortable, so I opted for a stock ring base which is alot easier to get the sizing right than an odd shape like a jawbone. Also smoothed the front teeth a touch and made them closer so I don't get sued for people cutting their fingers off.
